904, manual valve body, "drag free". Behind a mild stroker. (Iron heads, flat tappet cam) built by a reputable shop. Its always had a flare on the 2-3 shift when shifted at wide open throttle. A search of this forum says incorrect kickdown linkage adjustment can be the culprit. However being...

Please dont flame me if this has been thrashed out before, I've got a '70 aussie chrysler valiant sedan. The body's are very similar to the 67-69 dart/valiant/etc. (I'm not sure about the nuances between those models, as they were never sold here) About 15 years ago I had it all paneled and...

I'm looking for a pair of 302 heads. A family friend has a container leaving Seattle to come down here to New Zealand in a bit over a week. So the closer to Seattle the better. (I'm not a wealthy man, and iron heads aren't going to be cheap to send too far) Anybody able to help?

At what power level is a 904 no longer big enough? Here's the story. a couple of years Back My dad bought a drag free 904 w/full manual valve body from a reputable shop. The car is an Aussie Valiant hardtop. (Very similar to a 68 Dart) Runs a 340/418 stroker. In the time it's been in there...

My apologies if this has been thrashed out before, But we have a 904, bought from a reputable shop. It's a full manual valve body "drag free" (What ever drag free means?) 904. Supposed to be a pretty good unit. According to the shop who supplied it. However when I'm racing, and really have the...

Sorry if this has been discussed before. But when fitting the offset upper control arm bushings, Do you fit them to the front, the rear, or both bush pockets (With diametrically opposed offsets) in the arm? They're sold as a pair. So I was wondering if maybe running them both cranked up the...

Im looking at building a custom three carb manfold for a 225. A mate of mine works at a place that can do wate jer cutting of the aluminuim for the flanges. Ive got gaskets for the carbs. But I don't have a spare manifold to copy the flanges off. (Its still on a running car) They charge $100 to...

My dad kindly let me run has valiant at the Drags, Saturday just been. Aside from the huge wad of cash he's sunk into the motor, Trans,and converter, the car is little changed from how it was when he first bought it back in '81, or '82. (I must have been about 5 when he bought it) currently...

What real world experiences have you guys had with upgraded valve sizes on a SBM with a 3.940 bore and small port heads? "Conventional wisdom" says that 2.02's suffer from shrouding. Yet plenty of guys have slapped J heads onto 318's. (Biggest hurdle there is getting over the miserable...

I did some racing last weekend. Motor threw the fan and powersteer belts. On the last pass, it also lost one torque converter bolt, and stripped the helicoil on the opposite side. Motor is a stroker. Given that there were issues at both ends of the crankshaft, could an imbalance issue be...

I ran a 340/418 stroker at the drags yesterday. First run it spat the power steering belt, and turned the water pump belt inside out. We left the power steer belt off for the day. (After all, that power steer pump is stealing horsepower) But next run it spat the water pump belt right off...

I haven't posted here for a while. Yesterday was the last drag meeting of the season. (southern hemispere life) I haven't raced for at least four years, on account of having a couple of little kids, and the car I used to race in Just got too hard to keep up and running. So with my extensive...

a couple of weeks ago, myself and a couple or mates went to a party. One of the mates is from the other end of the country. The party was also a beer pong championship/tournament. One of the mates I went with actually lives at the other end of the country, and I don't see much of him. We...

we've got a 340/418 stroker motor. Which is still pretty fresh. but it's blown a head gasket. In spectacular fashion! I've not seen a gesket pop this severely before. So am looking for some insight into why it did this. motor has brand new RHS heads from Brian, and the decks were machined when...

Are the valve bodies on SB 904's all interchangeable? or did the change things around on the newer stuff?

I'm in the market for some thin as sbm head gaskets. I had a nosey at Summit, but I'm lousy at computers, and couldn't find anything. Plus I don't buy from Summit as a rule. I'm far far away from the US. I have a mate who owns a speed shop, but he's selling up soon. So I want to have a spend up...

Last night we tried to give a new motor her first fire up. After the obligatory problems that always seem to go with a new engine, it burst into life. Oil pressure came up instantly. But the motor made a horrible clacking sound. (I wish I'd taken a video) It has a remote oil filter. Our RHD...

Whats the best solution for a nice performance air cleaner to run on an Edelbrock with an electric choke? We just tried a nice K&N, but the choke body fouled on the air cleaner base. What has everyone else used? The motor is a 418 stroker, with a pos knock off air gap. In an Aussie assembled...

Today I got a 318 core that I picked up for a $100. I bought it back in January, but it was a 7 hour drive away. So I had to wait for a tool rep mate of mine to pass through that end of the country to collect it. (He reckons I owe him a new back after he tried to load it into the back of his SUV...

I was rereading "how to big big inch small block mopars" last week. The guy I borrowed it from wanted it back. (Thanks Dad lol) Anyway, it mentions the V10 conrods being made from the Magnum forgings, but machined with the C2C being just a fraction larger. With motors running a 4" arm, the...

hey guys, anyone know what these numbers mean? MH340R(?) (I think it's an R, the numbers are getting hard to see) then 38330001. and the casting numbers on the side are 2780930-340-2 And the other side has 9 28 71. (Which I presume is the casting date?) It also has R and a 3 on the...

Bit of a newbie honing plate question, When an engine is being honed with them, does it need a plate torqued down on both banks? Or just on the side being honed? I realise that While cast iron isn't as ridged as granite, (Hence using honing plates) but it is standard practise to have the main...

Just out of curiousity, is there any reason why one couldn't use 5.2 Magnum pistons, in an LA 318? Magnums are next to non existant in my part of the world. But I was mindlessly surfing and I came across a set of Magnum pistons with a 1.755 comp height. (Flat tops too) Now I've heard that...

I came across this auction, http://www.trademe.co.nz/motors/car-parts-accessories/chrysler/engines/auction-527624548.htm But I've never seen SBM heads like these? Is the seller mistaken? Or are these just some head I've never before? (Anythings possible, there's plenty I've not seen)

I need your advise team. My dad has decided to stroke his 340. It's developed a nasty knock if the car is driven faster than 42mph. Before he fitted the engine to his car, it sat in a loft for 10-15 years. A friend his his from back in the '60s had run it in a class winning Marathon boat, back...

Has anyone done this? I have a small drawthrough set up with a roots blower and a holley carb. A mate of mine is doing a similar thing, but he seems hell bent on going blowthrough. I've explained to him what needs to be done to his carburator to support blowthrough. BUt the more I think about...

Hopefully someone here can answer my question. The forum I used to get my supercharger info from has dissapeared. Anyhoo, Does anyone here know if it matters which way up a 4/71 is mounted? I run a small toyota blower on a wee japanese in line four pushrod motor at 90* to how it was mounted in...

I came accross this http://www.trademe.co.nz/motors/car-parts-accessories/chrysler/gear-boxes/auction-423477969.htm while surfing tonight. I did a google, but I've not been able to find what's included. I'm guessing it's seals and gaskest? I scored a 904 in bits for $20 (Was alegedly a good...

Most of you guys have probably heard of the Aussie A body chargers. Here in New Zealand, (Where our racetracks are a bit shorter and tighter than in Aussie) The chargers were a formidable force to be reckoned with. A bloke I know recently made a short doco about these awesome cars. With some...

Im real new at head work. In the past ive done nothing apart from get a shop to replace guides, seat inserts, and recut seats, and valves. And I've lapped valves, and shimmed up my valve springs to get the correct pressure. But I now need to get my heads sorted out on my 318 before I proceed...
