I drove one and that’s with stamped rockers and springs that had about 100lbs on the seat IIRC..

The difference from a hydraulic cam engine to a solid cam was like night and day.
Please tell that to NHRA, the solid lifter engines were penalized with HP from the factory and now that all the hydraulic engines can use solid lifters they didn't get HP. But the solid lifter engines didn't get a reprieve of HP.

Really really hot here at VMP, made a clutch adjustment and two test runs today. About .05-.07 slower than our test last week but Good weather is on the way. Too hot so I'm going in the a/c for a bit then doing carb work tonight. Shot an in car video and you can clearly hear the car labor in high gear till maybe 6100 then takes right off till about 6900 at the finish. Making some shift light adjustments for tomorrow.

1967-69 Z/28 302, 290 HP from factory, 309 NHRA Factor. That same 350 that you mentioned, only has to weigh only 110 lbs. more than the 302 in E/S. 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 !! 😂

That’s awesome ! That dyno you tested the engine on must be awfully stingy on readings or something changed a lot. Those engines generally pick up a lot in good air. Good job !

Yes, I was told the dyno was not a hero machine.

I'll assume the air will be better here on out, I don't know about the car but I know I'll feel much better about it.
