I may be getting a 390 fairly soon, and want to know if there are any worthwhile mods to make to a stock 390.

Ive been told and read countless times that this engine is "torque-y but slow"

First off, ive seen something about a 428 crank which would bring it to 410 C.I - would it make a difference ?

Any ideas welcomed.

Thanks,

Gary

You really need to speak with Cougar. He is great when it comes to FE series engines. I know there are some oiling mods you can do, and if anyone could make a 390 FAST.... which I dont see how it could be slow anyway, It would be Cougar. You should private message him.

as far as making the 390 faster...you can do a few of the following:

1. go with a 428 rotating assembly since the blocks are essentially the same

2. use aftermarket heads (edelbrock makessome pretty nice FE heads and they flow much better than the fomoco castings)

3. go with a more aggressive cam

4. go aluminum intake (lighter means less weight for less wait...you go faster sooner)

ignition I prefer MSD but to each their own..plus I like MSD tech support and service...never a problem.

A good pair of full length headers

a good carb size.....750cfm and above....if your cam is not that aggressive vacuum secondaries are in order...if too aggressive mechanicals are better.

how fast you wanna go depends on how much you are wiling to spend
