WTB 1973 Q code 351 cobra jet engine
#1
I'm looking for a stock engine for my 1973 Mach 1 Q code. Will buy or trade a freshly built 1970 351 Cleveland 4V producing over 400 HP. Engine runs great it is not what I want for a daily driver.

Why not just detune the engine,unless you are doing a concourse resto? Just a thought. Sounds like you have a very solid engine already. There is not much differance in the engines, basicly a head change,if you are running closed chamber heads.

Finding a 4 bolt main 351C block that isn't already .030 over bored can be difficult and will not be cheap when you find it. Taking one to +.040 is really pushing the envelope with these blocks. The cost of the other parts and machine work will grow very rapidly As FAstE said a detune would be easier, faster, and cheaper. Chuck

I have an original Q code motor in a 74 Torino. I don't know how many were made but its probably a leftover 73 motor. The whole drivetrain is original. It has a C6 and a 9 inch behind it. Just PM me if your interested.
