    Hows it done? I know Mech E-7s weren't around long. 1st when we inframe it were going lower comp pistons off the 400. 20% bigger injectors from rochester and either 400 or 427 turbo and have a pump off a 400 and have it tuned on a dyno correctly. Already has full gauge package pyro works good.

    Please any suggestions my dads never converted an e7 vmac to manual pump. He knows the e6 and 7s inside and out. Hes gonna retire soonish (10-15yr) he wants to go out old school and wants a stump puller for his last ride. Gonna have 13 over 3.91s on lo-pro 22.5s

    800k now and no blow by my dads throwing a blixxton on it to bump it around 440ish. 1250tq in the mountains is going to be painfully slow with the 9sp and considering the 300+ had 1425tq
