You don't want a cam that's going to make your compression worse. Also the RPM is a great intake but unless you are going to do more to the engine later you can get by w/ a cheaper dual plane like a used Holley SD or Eddy CH4B.

Definitely keep the cam short duration and designed for low compression. Recurve the distributor to get more initial advance and a quicker advance curve.This will help the bottom end with low compression. A 750 vacuum secondary will gain power over the 600 in the mid range/top end(lol it will be done by 5000rpm if not before).The 600 however will be fine for cruising and stoplight burnouts. LOng tube headers will be a big improvement everywhere. MIght make 360hp and 450lb ft of usable torque.

With either the either the XE256 or 262 cam you are looking at around 300 ponies and 450 lbs ft of torque depending on which cam you use. I used the smaller ones for more torque. This factors a 850 cfm carburetor, standard flow intake, and small tube headers.

I was planning to rebuild my 440 but couldn't make it happen financially so instead of letting all my parts sit I threw them together to have some fun with: Stock 76 440, hone'n're-ring with new cast pistons 440 source heads Lunati Voodoo 60303 cam Summit el-cheapo headers Stock intake w/ thermoquad Recurved distributor Stock converter and a 3.55 rear gear Never had it to the track but tooled around with it a lot around town. Made a decent amount of power and enough to put on a good show when I nailed the GO pedal. Popped off the header cutouts and guys would come up to my car drooling, then grinning ear to ear after after I filled the area with smoke from doing a few hard launches and some doughnuts. It ran decent for what it was, however I figured the stock intake was holding me back and a bit more gear and converter would have made all the difference. A recurved distributor is a MUST. That combe needed a lot (18-20*)of initial timing to run properly. Throttle response during normal driving was good, almost as good as it was when I had the stock cam in there. I was pretty satisfied with how it ran all things considered.

If you want the RIGHT cam for your combo. BTW, have any of you cam experts ever run a low compression motor with a cam that on paper is too "big" for the actual compression?

It was literally a $200 junkyard motor and trans. We left the stock pistons, rods, crank, bearings...everything. We put in a used .509 cam and lifters, Team G single plane intake, 750 Holley, TCI 10" converter, and 4.56 gears. The car ran 12.80's like clockwork. We then freshened the 452 heads and put on a Max Wedge intake w/ two 600 Carters. It ended up running 12.40's @ 108 mph. The engine would just not give up...it still ran when we pulled it in the late '90s for the 'good' engine. The short block is actually still under the bench in my parents garage. We all joked that it did not have enough power to blow itself up. Oh yeah...the compression worked out to be 7.8:1 in the good cylinders. 6268466-DSC00792.JPG (50 downloads)

Found a pic from the early 90's. Looking back, I can really tell how bucks down we were. 6268471-64Engine1994.jpg (84 downloads) Last edited by Blues_Cuda; 10/25/10 07:02 PM.

No compression and 12.80s would make me happy, id be able to beat almost all my friends cars, and it would run on dog water

A member on here (forphorty) has a low compression 440 (high mileage short block also) with a 292 Comp cam, Torker intake, stock valved 906s (chambers were polished, so compression is a hair lower than stock), headers, 750 DP, 3500 stall, and ding ding.... 3.23 gears. 3500-3600 lbs.

I would get the distributor re-curved and run a good coil with an MSD 6AL or go with one of Firecore50's ready to run setups and the best headers I could afford sized for the combo. I would save my $$$ and keep the stock intake and Thermoquad carb. Unless you get the heads ported or go with Edelbrocks or something it will be out of any serious steam by 5500 anyway and the stock intake much as you might hear to the contrary is as good as anything out there up to that point. It should do 1HP/cubic inch give or take easy. Kevin Last edited by Twostick; 10/26/10 11:20 AM.

On thing that you may have to do is trim the tops of the valve guides down I had retainer to guide issues with a 509 and 452 heads.
