I need to know the depth of the single groove pulleys for the crank & water pump on a 69 & earlier small block. There's a member here who has some water pump pulleys for sale with different depths & I need to make sure I get the right one. I might also need a single groove crank pulley but...

WHAT HAPPENED????? I was going to buy a set of offset keys so I could degree my cam when I assemble my stroker. I thought the price was a bit high because it was somewhere between $35 & $40 for a set of 5 but that's the breaks. But now all I can find is the Mopar Performance set for almost...

Has anybody here ever used the Milodon 18650 oil pump pickup tube? It's designed to work with a stock style small block center sump oil pan. I'm trying to find out if it's a less restrictive tube than the stock tube. Summit shows a pic that looks good but says that it's just a representation...

I'm accumulating parts for my 408 stroker build & starting to second guess myself :read2: so I thought I'd ask for your thoughts. I'm putting the engine in my 64 Barracuda. It will have a 91 roller cam block & Comp Cams roller cam (230/236*@50 110CL 4* advanced w/510/520 vlift, 1.5 rockers) &...

A few of the people here on the forum know about this, but I'll start at the beginning. In September of 2007 I bought a balanced 360 LA roller cam short block minus cam on eBay. It had reworked rods with high strength bolts (ARP? don't recall at the moment), main studs with a windage tray...

Does anybody know if the Comp Cams roller rockers for a small block will fit under a stock valve cover? I have a set of Commando 273 valve covers I'd like to use. I'm also wondering if anybody has an opinion on these rocker shaft hold downs. Overkill with a spring that's rated at 320...

I plan to build a 360 using a 1991 pre-Magnum roller cam block. This block has the oil passages drilled for the shaft mounted rocker arms on the LA cylinder heads I'm going to use. The block also has provisions for oiling through the pushrods like the Magnum engines. I'm also going to use a...

I have something I want clarified for me concerning aluminum heads. We all know you can get away with a higher compression ratio with the same fuel octane when using aluminum heads. I've been told that if you have approx. 9.5 to 1 with an iron head you can use about 10.5 to 1 with an aluminum...

How do I tell whether an aftermarket Magnum camshaft has a short snout or a long one? Can somebody give me a measurement? How much difference is there between the two types? Knowing the amount of difference in size BETWEEN the two won't help me now, as I don't have anything to compare to, but...

I'm always seeing that you need to use a bronze gear on your distributor/oil pump drive when using a roller cam. This is because one of the gears will get chewed up otherwise. Is it the pump drive gear that gets chewed up or the cam gear? Why does it get damaged? Does this apply to all...

Can somebody give me a ball park figure for the maximum valve lift a stock J head will handle before you need to cut down the guides? I seem to remember reading way back that it was around .510", but I'm old, so my brain doesn't work as good as it used to. :sad1: How much clearance is...

I found an article in the July, 2000 issue of Mopar Muscle on a 360 buildup where they got 430 HP & 420 lb/ft of torque. Unfortunately, this is the last article in a series & I don't have the rest of them. I went to the Mopar Muscle Tech Archives but couldn't find it there. Does anybody have...

Is there a way to determine the date, or approximate date, that a cylinder head was cast? I have a pair of 915 J heads. I read in the Mopar Performance "A ENGINES" book that pre 72 heads need hardened exhaust seats added, but the 72 & later heads already have them. My heads have 360 cast into...

I just bought a 360 block with crank, rods, etc. on ebay (I hope it turns out to be what he said it is) with a .030 over bore with flat top pistons (Sealed Power H116cp) with about .006" positive deck height. Can anybody tell me what approx. compression ratio would be with my stock J heads...

There is a guy here in town who scraps cars & has a 360 that I could buy cheap, probably for it's scrap value. He said it was a "new" one but it has been sitting outside in the back of a pickup with no air cleaner for a long time. I don't know what he meant by new, maybe it was a replacement...
