HHHHmmm. Yes it does seem like it's a little low. I cant think of anything else aside from the motor being 37 years old and it was 33 with about 94K miles when I modded it. Ok... The run down: Holley 650 DP Ported Windsor heads 1.94/1.60 Air Gap dual plane. Electric ignition (MSD) Longtube headers. 2 1/2 exhaust H pipe. Flowmasters.. Old school cam research cam. 108 lobe .510 int .515 exhaust. 224/232 Dur... I think I smell the culprit 3.70s in the 9" T-5 I vote for the cam. Yours is a roller probably far more efficient. My 331 has a Comp 274HR. Just gotta put that damn thing in.
That's friggin awesome! My old 306/TL 4 speed/4.11s with 700 DP got less than 10! The cam was 228/235 on 110*... awesome grind BTW! Just couldn't expect it to pull before 2500 rpms, but the WR toploader and 4.11s made 2500 rpms come FAST.
How can I make the 302 motor faster in my '71 Comet? I have a 1971 Comet. I'm working on rebuilding the body. I'd also like to make the motor faster if possible. It is the regular 302 motor, automatic. Does anyone have any tips? Thank you Thank you all for the advice. Here is a picture of my motor 302 that i want to make better. Thank you for the help!
I just realized that I wrote "standard" but my car is really automatic. please just let me know if any of your tips won't work on an automatic. sorry for the comfusion thanks again.:Handshake [ame="http://www.youtube.com/watch?v=idkFpJ54WYQ&feature=related"][/ame]
I gave mine a good tune up, advanced the timing to 12 degrees, put on a 500 Holley 2 barrel, and dual exhaust. With a stock tranny and 2.79 gears, it would chirp going into 2nd gear at about 45 mph.
By themselves headers will not increase power much but if you add a 4 barrel manifold and carb and a mild cam it can make a big difference.
reminds me of someone i use to know....ME! if your still in high school, take the auto classes, ive spent about 3 weeks in it so far and i learned alot
i think those headers have oval ports. got to be carefull when ordering headers that you get the right port shape.
Your carb is a typical emissions style carb. You would get more out of a carb for a 69 351W 2 bbl than from the one you have. The difference is that the accelerator pump has a bleed hole back into the bowl on yours, it is jetted lean enough that you could get a lean surge at freeway speeds. The 69 carb has no bleed hole and it has jets that are about two sizes larger. It won't hurt fuel economy (it might improve) and drivability is way better.
