Default New 383 setup

Need some food for thought on my new setup...Im moving from a 346 to a hke 383 which with my 317 heads and a stock head gasket will put me at 9.18:1 compression.....also moving up from a s trim to a T trim and plan to spin as fast as possible...My question is should i mill the 317 head a little and run a thinner gasket to get to 9.5:1 or should i run a ls6 head which will put me at about 9.9:1...I just dont want the car being sloppy and lazy out of boost...not really sure how much boost the t will make but with a 3.125 pulley and a 10% overdrive pulley im sure its alot...also as for the cam its an a&a 220/232 on a 116 should i keep it or move to something else....rest of the setup is in my sig

Run the LS6 heads and keep your cam. I have close to that cam and it will make more cylinder pressure down low and the boost will carry you up top.

Another option, is to just deck the heads, and leave the gaskets you plan on running. This is about an 100 bucks worth of work. Unless your cams lift is crazy, your not going to run into piston to valve issues. With 317's, you can get there.

Personally, if the motor is out, or the cam is accessible, i'd swap it out to a 232/240. That is a very very successfull blower cam. Some tuners even call it their "Blower" cam for 347-402's.

I'm not a big fan of milling stock heads on F/I engines. You need all the deck thickness you can get. That cam you have is one of Andy's blower cams. Driveability will be great and if you turn up the boost and tune it right you'll make great power I guarantee it. If I'm right, you saved the cost of a cam. If I'm wrong, you have a cam purchase, a weekends' work ahead of you and if we ever meet, you can smack me across the head.

I had a LPE 383 with 11.1 CR with 241 heads GT2-3 207/220 running 11 lbs of boost in the nines. The car felt great off boost with the higher CR.

Default timing chain cover

You can get a eldelbrock two piece timing chain cover from Jeff for a great price. That is where I got mine and it looks awesome and I think it will be just what you are looking for. I hope this Helps Jason

The member jjformato (I think thats how you spell it) is selling a QTP timing cover for like 350 bucks in the F/S section. That would be a go deal. I have one on my car, and love it.

If not, we have the edelbrock covers for less than 200 bucks. They are a really nice piece as well. Excellent part for the money.

I am aware that is one of Andy's blower cams. But since you were turning up the wick on a 383, IMHO, it's a little small. You'll take better advantage of the output of that blower by going with more duration.
That being said, cam swaps are a piece of cake with the 2 piece cover. It wont hurt to try. FWIW, although the stock decks are nowhere near the optimal decks, shaving a few thousandths off, wont be any more detramental than what you currently have.

No matter what you do, its a win/win, and you will be happy with your car. Be sure to post your results when your all done.

I wouldn't deck the 317's, best bet would probably be a LS6 or LS2 head like Bret suggested.

If your using a overdrive balancer like the IW, I don't think you can swap cams even with a 2pc cover. That being said, if your happy with that cam keep it, it will work.

Both of these guys are spot on, get some LS6 or LS2 heads and be done with it, milling and high boost do not go together well. Your cam will work, I make 750 in my 347 with a very small A&A cam, boost is your friend here

My money would be on the ported ones. They should still come with some good springs and pick you up some 'free' HP (since you said the price will be close).

I am running stock 243s on mine, couldn't afford ported ones. This is on a 402 setup. I am sure this will kill a bit of my top end once I figure out my belt slip issue. I picked them up with comp duals for 6 or 650. If I could have done ported I would have but I was absolutely not going back with stock 241s

Good luck!
