My New 540
#3
Thanks,
86 Camaro. It ran 9.30's last year with a n/a 509 motor. Hoping to go high 8's with this motor, but I'm thinking it'll come up a little short. Over 3 tenths is probably to much to hope for. My next motor will be procharged or turbo and more streetable.

The 540's heads are fairly small. They're old Dart 320's, but flow over 410 cfm. I've had the heads for 6 years. If I was buying now, I'd buy something different. When in doubt I've always went with smaller heads and it has always worked pretty well. I don't like spinning a motor to 8,000.

i think you think he said head, but he said a bigger header??? maybe i'm wrong, but you never mentioned anything about the headers after replying with his quote. i for one think that those are some good size primaries there, but i'm used to small blocks. lol.

I've had the headers ever since I had my 461 motor in it, so spending a grand or more on new headers was just not a priority. They are not really that small for a 540 though. I had these crappy hooker 1-7/8" with 3" collectors on my 461 and put these on and it didn't run much better, lost a little 60ft and picked up a little mph.
