X block, 4" stroke 360-1 Indy head build questions

Just my opinion, but a roller cam will give you more power at just a bit more money especially if you already plan to buy lifters. I've talked to a few experienced guys locally to me and they recomend a hyd. roller for a street/strip type deal and a solid roller for more strip than street. They used to run solid tappet street engines, but you'll have to adjust your valves weekly. That said, I am looking forward to seeing what you end up doing.

And I agree with ou812...pump gas now isn't of the same quality as even a year or two ago let alone 15 years ago. 10.5:1 is a safe limit now
