Don't recall the lazy performance post, been too many negative ones I try to forget... I was told these cams will cause me issues, but at the same time the people that told me that have yet to show proof of it... and I am torn on what I will be doing, changing them or keep running them...
sick of taking engines in and out of the boat.. |
gotcha, will be looking into it I am sure... yay...

Check spring pressure should be around 20psi less than new spec. Springs typically drop 20psi then set in and keep that pressure. If its 40-50psi or more less than the new spec I would change cams your lobes are killing the valvetrain

Here is an independent test I pulled off of Stan Weiss. At the lower lifts the numbers were better, higher up the flow was slightly lower. The flow numbers start at .1 and go to .9, they are in .1 increments.
AFR 325 Weingartner Racing Brez N/A 2.30/1.88 4.31 No Pipe N/A 81/63 166/137 236/182 293/226 340/258 358/274 377/280 383/282 386/282 |
Are yours done now Tim?
|
Yes, waiting for more numbers and info hes been busy

Cool!
Progress is good. Now time to pick springs and figure out the cam. Any word from cam motion? |

I didn't do a "before" number but here's what they are. Now [ATTACH=CONFIG]563024[/ATTACH]

Would have been nice to see what they flowed stock, then ported.
Thats with a pipe on the exhaust, so keep that in mind when comparing flow numbers to other heads. Most are not flowed with a pipe, and will show less cfm without the pipe attached |
