TFS 325's to much

Post  slowjoe on July 30th 2015, 4:42 pm

I have a 437 short block that I will be putting in my car to replace the stock 429. My plan is to do a 545 in a few years. How bad will the 325's and big TFS intake hurt the 437? I was hoping I could just swap them to the 545 when I have it and the car setup better.

They will work ok, just make sure to use a looser converter, a little gears and don't go overboard in the cam.

After doing some reading on here It seems I can't turn the stock rods much over 6000 rpm. Was planning on have a custom cut solid roller for it. I am also planning on about a 150-200 shot sometimes.

Any over headed engine you need to narrow the separation up on the cam. Put some overlap in it if your running it N/A.

If you are spraying it, go ahead and cam it like it was a 545-557. And spray tha bag off of it.

But if you have stock rods, you better run it N/A till you can get a set of good rods or the bigger engine.
