    I finally have enough money saved to replace my tired 350. I need advice on options. I was looking at chevys new 350 Ramjet crate. I just put had my 700R4 rebuilt (Corvette Servo, kevlar bands... The Works) I want a motor with more torque as I pull a heavy trailer from time to time. The Blaze is a daily driver. I already swapped out the gears with 4.11's. Running 33 12.50's. The problem with the Ramjet is it has it's own ECM and you have to by a seperate transmisson controller from Jet. The o2 harness would also have to be purchased from Arizona Speed and Marine.

    Isn't there a decent crate out there where the stock ECM can be used. I just spent $130 getting my speedo recalibrated.

    Thanks for helping,,,,,

    Don't have the time/tools/space to do it yourself? Sorry, can't help you out besides doing it yourself....aren't there any hi-po crate motors that take the same intake pattern you have? Maybe you could have a machine shop build up one for you? They typically have blocks laying around that people never paid on, etc.

    I'd look into 377 and 383 stroker motors... both are very torquey and will give a lot more power then a 350. 383 short blocks generally go in the 1500 range or less... bolt on some good heads, headers, etc and have a custom chip burned and you'll be set... that is what my plan is gonna be
