Search results for query: 318 cams

383 Magnum was rated at 5200 rpm. If you couldn't get your 383 past 4000, there was something seriously wrong with it. If you couldn't get a 383 four speed to roast tires better than a 318 2bbl, there was something SERIOUSLY wrong with it. (I would guess trash valve springs, or a flat camshaft).

You do not need to go as high as 050 tappet lift to determine if it is SFT or HFT, will not tell you anything. You measure from zero lift to about 0.020 lift. It can be really difficult to get a definite answer because the line between sol & hyd has become blurred over the years, with some...

Not all that useful experience to mention, you said yourself "assembly line stock". I agree in that form they're weak and burn up easily. Fried my original stock one behind a 318 that probably didn't even make 250 HP. If they were truly junk transmissions though I don't think Chrysler would...

I’m not going to lie this might be too much detailed information for me to comprehend. Time to figure out what all of that means.

Cams for 318's

Gotta love those "Thumper" type cams. They call them poser cams because they idle like a top fueler but smooth out at 2000 rpm like grandma's 318. Just the perfect thing for cruising around the car show. Here's one now. A 318 with a Whiplash. Love the sound for sure. Great looking car as well.

Thanks for the input! Greatly appreciated. The main reason I mentioned the vacuum is because I was already looking at other cams since I may be over-cammed for my intended build. If that purple cam I already have will be fine, I'll just run it with the 9" of vacuum. Like you said, you never use...

My question has nothing to do my cars gearing stall etc.. I was looking over 318 builds for another thread, the guy was really worried about bottom end torque, conventional wisdom on here bigger cams heads etc.. gonna kill low end torque especially with a 318 and make a soft gutless dog of a...

For the 318, would the lunati 701 be a good choice for what I'm wanting to do or the 700? I used a compression ratio calculator put in all the required information and it said that I would have a 9.40:1 CR. Is that a good compression ratio for either 1 of those cams? I don't want to have to back...

Already knew i would need 2 cams.. massive difference in 318>390.. This year will just be stock bottom end 318 with heads/intake/headers, 3000# car with stock converter and for now and 2.76s (gonna be granny cruisin for a bit) That's why the very mild cam... reason to go big and not have any...

Why is it only got a 1000 rpm powerband ? Any time I've seen a mild cam swap over low performance stock cam the gains have basically been everywhere they measure 2000/3000 to 5000+ rpms, not just the top 1000 rpm. Why? Your saying a 48* vs 51* is gonna murder the bottom end ? What about if...

Im leaning towards the first one as well, and in reality this is to be a cruiser, so I will most likely end up with the gears in the 3.0x or 3.23 range. Using stock rockers means no adjustability....does that mean id use the stock pushrods too? Again, this kinda thing is all new to me. As for...

My engine builder has suggested the Comp Cams XE-250 or the XE-252. Since I'm cam "dumb" I would appreciate some guidance. Some details about the car/engine to the best of my knowledge: The machine shop performed an .030" over bore on the cylinders, polished the crank and added(?)...

I had some questions about cams and this thread seemed like a good place to post instead of making a new one. I'm new to mopars and old cars in general. I'm used to DOHC motors where replacing heads and cams are almost never done due the cost and complexity, so I know next to nothing about cams...

Can't help myself. It looks like a fun cam. Have you used it?

I've done this swap a time or two. I have used the stock 340 short with 318 heads, and I have used both a stock 318 cam, or a stock 360 2bbl cam; installed straight up. I used a Factory cast-iron dual-plane Small-port, spreadbore intake with a Thermoquad. This makes your 340 basically, a...

All good points, but in his case there is no shop, there is no car, and probably there is no engine. No pistons will be bought, only complaining about a lack of options- same as when he is discussing buying a car.

I have the 108lsa version. Not the best for boost.. but whatever it's what I have.

My son has a Performance Engine Machine shop. He gets pistons for anything he is working on from his suppliers. No matter what engine you are working on you will need to have all the measurements to order the pistons. Not just send me 318 pistons. You will also need to have the block prepped...

Gonna give it a shot and see how wrong i am :) More overlap allows a better cyl fill which means more cyl pressure allowing more power, up to a point in which reversion would cause more issues and loss of power. Also depending on the combo/port design less overlap would make more power since...

Thanks, That's a great article for any Teen owner that want's a little more. I bet just a little head work and 300 horse would be on the dyno screen. That would be fun in any A Body.

My impression of an AJ response!: Not sure where you want to compromise regarding fuel efficiency, performance, and budget -the first two categories move in the opposite direction. Much of this is obvious but for review: More gears in your transmission, with a steep first gear so you can run...

You should still check fuel pressure.

You'll never notice the difference going to a shorty header. People spout off what they've read in magazines and forums for way too long. The simple fact is, you'll never spot the difference. Check out Hedman 78500.

I have been running a Performer 600 on my 289 and a Performer RPM Airgap manifold. Fuel economy was pretty good with 2.79 rear gears. I am rebuilding the engine and will install the annular boosters from the AVS2 650. The secondaries are where the extra CFM come from. I think it was The...

Maybe so but, per the factory literature a 318 in 69 was rated 230hp@4400IIRC, (which is only 193 ftlbs torque) and 340 ftlbs at 2400 rpm : whereas the 340 didn't get to 340 ftlbs until 3200, and peak power of 275@5500 translates to 356 ftlbs. Engines do not make horsepower. Engines make torque...

Now there was the qualifier, "among other mods". To properly compare and assert something you need as direct a comparison as possible. About 25 to 30 yarns ago, PHR magazine did a series of tests to compare 383 Chev builds. They rebuilt a 350 and dyno'd it. Then they put a stroker crank in with...
