lsx engine ( need advice ) Hi Guys
i need your advice on my friend's project :
before he used on his corvette c4:
stock ls7 engine + High lift cam + Q.F 1050 carb. + GM intake
(1/4 mile ET =9.6)
Currently his project is :
lsx 454 + stock ls7 heads + High lift cam + GM intake + Q.F 1050 carb
compression around 11.5
(1/4 mile ET =10.2)
finally 10.2 ?? is it logical ??
