Gotta give the customer what he wants.

Tyler when do you think you will have them ready for the market?

We should have the model cores done next week then they can pour them. I added a little thickness to the top so we can also bolt a supercharger to the top. I hope to have a finished part in 3 weeks.

Will these work on a 502 mpi?

They will only fit the 500 and 525.

So what kind of an increase can a stock hp500efi expect? Any idea on cost?

ttt any news

I talked to my freind at the foundry last week and he promised me a top by the end of Jan.

I did not try it on a bone stock 500 efi just one with bigger cam and better heads where it needed more air. It picked up 35-40 HP and Torque on the one we tested.

The stock heads are the first thing that should be changed on these 500's.
