Alright guys, looking to possibly wake up my combo a bit, probably to do more down the line, would like some critiques/suggestions.
Motor as it sits:
357 cu inch
350- .040" over SpeedPro flattops, 4 valve reliefs(I assume 2cc's per relief)
Ended up not zero decking the block, but the deck has been shaved a little bit.
RPM airgap intake
750 cfm vac secs Holley(3310)
RPM aluminum heads, 64 cc chambers head gaskets are the E-brock recommended Fel Pros believe the compressed thickness is .039"?
Cam is 302 adv duration 240ish at .050" .509" lift on Intake and Exhaust Hydro. 108 lobe sep. (One of the older grind SSI cams that PAW sells)
I believe compression is right around 10-10.5:1
When I did the motor I got in a snag for money and had to sell my Continental 3k stall. So its a stock converter with a TH-350 trans
Rear is a 3.36 pegleg 10 bolt.
Though I know this combo is badly mismatched as it sits, the car does run very well, I just know there's more in it, and as I approach graduation from college I'm lookin to tinker with some things.
Would say a 3k stall with 3.73 posi- 4.10 posi be more of a matching combo to the motor thats in there? Would I still need to recam?
When I was building the motor, I had picked up that cam(engine builder recommendation old school racer"gasser" building type) along with the Ultradyne that a number of you guys suggested, the 276/286H12 lift is an even .454" on that cam intake and exhaust. The guy really liked the other cam better as he knew I liked the aggresive sounding lope and whatnot so thats what he stuck in.
edit- I should note, at the time my motor was being built, I had a line on a 4.10 posi rear that I was going to pick up, and I still had the conti 3k stall, so the engine builder wasn't really planning around a 3.36 pegleg and a stock converter.
I just know this combo has something more in it, just looking for a lil more pep I guess. Just kind of curious if I should up the stall and the rear gear, or if its definately a re-cam situation.
Ultimately I'm just looking for an aggresive sounding quick street car. I rarely go to the strip anymore.
Any more input needed, just ask, and thanks in advance for any replies!
