DZ302 engine horsepower rating

My 302 with the crossram is totally stock, with std bore etc. It dyno'd at 359hp. If the xram is worth 25hp, (per factory) then mine would be 334 hp with a 4 bbl. I run an M20 with 5:38's. This year my best 60' time was 1.80 and e.t. 13.01.

Guys were running 302's in the early 70's at 11.00 flat in AHRA. Gene Dunlap had these times with his Harrell 302 GT racer. I calculated that my car had around 450hp when Fred had it, based on a weight of 3200 lbs, and times of 11.75 in the 1/4.

ps. I have only driven one other car that was as much fun to launch and shift, and that was Matt's DH proto #2. Neither feel "slow".

Ken, The 538's say it all with a 254 first gear! In the mid 70's when my friends, Pete and Ron set the G/MP national record they had a 280" motor with a 6:17 rear and a 3:00 first gear. (Nash 5 speed). Also had a 50lb. flywheel. Car weighed 3400lbs. Went 11:00 at 126. 1957 chevy 2 door wagon. My theory on the small blocks is start with the gears and a good motor will take care of itself. When I would ride in the 375 hp BB camaros they felt like rockets, but when I would run them with my 69 LT1 nova I was right at their door. Ben Wenzel goes 10.60's with a D/S 302 67 Z/28. My feelings Ken, is that your car was one of the most Super Cars at the reunion. Talk about history! You car is Day-1 and never changed.

Thanks Sam. I've had a lot of help, especially from Dave Libby who told me the set-up that was used on the clutch and flywheel back in 1968. When I weighed the current 40lb Hayes flywheel and clutch set-up, it weighed 64 pounds.

The Wenzel's are quite a dedicated crew, I heard that Ben and Jerry MacNeish got to race each other at Indy last summer. That would have been some race to watch!
