Tuning a carb for 1st gear performance
As others have said,the intake is killing you.
I have a stock 318 with a Edelbrock performer,Edelbrock 600,stock gears and it will come out of the hole real nice.It is all about the proper parts and tunning at this point.
Cant say enough about the Edelbrock performer intake,that should be your next buy.You can find them for around $100.00.
