Are These a direct swap?

Have you thought about trying to throw together a cheap 393 kit?

If you just change the pistons out for bigger ones, and keep the same crank and rods, then you are looking at the $200 range in machine work. You also have to transfer the rods to the new pistons, and those wrist pins have to be pressed out. Probably better to have the machinest do that that for you. You won't have to rebalance the crank or anything like that.

Thanks Kurt

Those are made by arias still?

I have no idea lol

well the kit may be cheap but the machine work to increase the cubic inch's wont change. Its still probably going to come out to more then what I want to spend.

What Im trying to do is get more power, I want something in the 380 range N/A. By increasing the compression, Long Tubes, and 205cc Trick Flow Heads Im hoping that will be enough
