Started in August with the rebuild and it is finally broke in and on the dyno stand for a few pulls. Just looking for some guesses on HP and TQ. The engine specs are as follows:
73 400 block stroked to 461 ARP Studs for main caps Forged h beam rods and forged srp pistons cast crank 4.25 stroke and balanced Comp ratio is 9.3 to 1 heads are 4x 7h and have 2.11 and 1.77 valves X-over filled and flow 241 on int and 228 exh Cam is tomahawk TC-02-HF [email protected] 236/244 [email protected] 510/505 LC 112 Johnson lifters comp cams 1.52 roller rockers, upgraded rocker studs & polylocks custom length pusrods intake is a stock 73 Exhaust on dyno will be headers w/ 1 5/8 tubes timing is currently set at 32 degrees and plugs look perfect. Will use a 650 holley carb to start and have others to try if needed Engine builder said with the detail and percision that he put into the assembly engine would have no problem surviving at 6000 rpm. I told him it would most likley never see over 5500 but its good to know. what do you think it will put out? |
