Top End Miss
ok so my carb guy has a 750 Vac holley! so he is gonna give it a once over and then i will give it a try...
but here are some things i have been thinking about...
with the original 7.25 and the 3.91/suregrip it would it 6 grand like nothing, didn't lean over or anything... no with the 4.88's its 5800 and bam, shooting ducks...
now the 4.88's do a couple of things,
first and i think the biggest is make the engine rev alot faster... now that makes me thing more air and fuel (bigger pump and carb)
cam turns faster and so do valve events (bigger springs and pushrods) and
lastly with gears it is effectively taking load out of the engine by allowing it to spin faster... now could it be causing the cylinder to fill more but due to a lower load on the engine its just getting overly rich?
just thinking out loud here... oh and over advancing the cam? its a 106LSA installed @ 102...
