What weight do you run at?

The 302 is factored to 1.023 HP per ci, the 350 since it's basically the same engine just more cubic inches should have the HP factor of 358 HP fallowing the same formula. NHRA gave that engine combo a gift.

The LT-1 is indeed a Big cube Z/28.

My friend had a 70 Yenko Deuce and it was a very fast car.

Engine broke a rod and I put a Z race engine in the Deuce. That friend had a ‘69 Z racecar. I made some runs in that one. The Deuce was still very fast with the 302 in it, Street car with very steep rear gears.

Those 2 cars were probably my favorite cars I’ve ever driven.

The 69 Z would be worth a fortune today. Who knew !! 😂

I was making that comparison based on 1970 technology and what we had back then.

I really don't think there is anywhere near as much difference with what was being used for hydraulic lifters in the modern era.

My hydraulic roller cam/lifter equipped EFI LT-1 could rev to the moon with very moderate spring pressure. Maybe not the best comparison to a flat lifter cams but still hydraulic lifters...

Weather is cooler today but certainly not ideal, feels real damp. We tried to concentrate on keeping the car a bit cooler this morning and she made sure the 3-4 shift was a little late and ran a bit faster than yesterday. Don't pay any attention to the weather numbers in the photo, that's old info.
