Top Swap time. Small port to large port 3100 - need help.

remember, my manifolds I made....They already help a lot. I plan on getting on the dyno before the swap to see what I've gained just from them.

 

Matt, I put down 124 whp....~20% loss puts that at 160 chp, so right on par for stock.

 

Now w/ my Down pipe and manifolds, I can almost stay w/ him even though he is top swapped.....:dance: I hung right w/ buck to 80 when he had his 99 MC w/ the 3800.....I don't know if I had the manifolds at that time though.....

 

Yeah you had them on. And it was a 98!!! Get it right!!! LOL

I would just swap the 3400 heads on to it to make it worth your time. if you are looking for some let me know I have a few sets kicking around!:thumbsup: IIRC the 3400 heads flow around 20cfm more on the intake.
