I dug out the time slips from my last drag car.
78 Camaro
std bore 350 cast flattops, 461X heads 1.94 x 1.50 valves, valve job done on a Serdi machine, I ported the heads using David Vizard's concepts, 67 Z28 valve springs, Cam Dynamics 268 Hyd cam 228 @ .050, 480 lift; high volume pump to make up for too loose main brg clearances, .001 undersize mainbrgs to get clearances down to .003 > .004.; Moroso deep pan run 1qt low on the advertised capacity; stock cast iron dist converted to HEI magnetic pickup, recurved, MSD cap adapt, Ign coil and ign modules mounted on passenger footwell using msd firewall terminal for the coil wire. Jet Hot coated headers; Performer intake; 600 vac secondary holley. ARP rodbolts, main studs, head bolts, oil pan studs w nylock nuts and same for valve covers.
286 rwhp using a formula that takes vehicle weight, et and maybe one other parameter.
Turbo 350 that I built using a Transstar HD kit, hardened roller clutch race and a Transgo full manual valve body reprogramming kit. Cheap 4000 rpm stall torque converter.
4.88
1.75 5.11 7.99 @ 84.91 1/8th 10.51 12.67 @ 103.69 1/4
9.5x28x15 MT slicks
2600 lbs
Using the above HP formula the car was supposed to run 12.2 in the 1/4. The 4.88 was way too low for the cam. 4.11 would have been best. This car raced sportsman [ the footbrake class ] where 13.00 was the cutoff so we had a real battle to slow it down.
I had a set of Arias 327 domed pistons, a steel 327 large journal crank, a Vic Jr intake and a 750 Holley that I was going to put in the 350 block but never got around to it. My body wouldn't tolerate having it's biorithims messed with and racing at night means you don't get home until way late so I finally quit dragracing.
