[QUOTE=EZ Nova;9552225]So I know we don't get the specs of this engine, but what do you people "think" this motor make? I see corrected and uncorrected on the sheet.
402 with 11-1, hyd roller cam???? 702 heads with 219/188 valves with some work, holley 750?
We have for some comparisons:
Joe Sherman's 9.75 to 396 that went 557Hp,
now I made a thread about this one, yet no one seemed to dispute it.
Super Chevy's 396 Build, 10.25 to 1 with a 750 Holley made 577Hp, How to Increase Horsepower -Super Chevy Magazine
Our very own Mark Jone VORTEC PRO L-78396/375 build made 452Hp, 1969 L78 396 375 HP Dyno Test
Chris Struab 10 - 1 396 with OEM 702 and hyd roller and 750 made 450+Hp, now there are others in this thread, Vigg, that also had a 396, UNPORTED 702 head, solid roller with 10 - 1 and 750 and made 511Hp 10 to 1 396 with 702 GM heads
My old 396. NEVER dyno'ed but ran at the track ONCE in 1/4 to 10.47 @ 3300, and about 15 - 6.40 passes in the 1/8. I figure that was about 550-575 range.
Reason is, I want to do a 600+Hp (601 or better LOL) 396/402 based engine. I would like to use OEM heads and block. I think I'm going to get there and I have heard from both Gary in NY and Mark Jones that BOTH have done it and BOTH have 396/402's that have been over 700, so there is some HOPE.
Mine is as follows:
- 402 short block ('72 4 bolt block built to L-78 specs. , standard bore, GM crank and rods, ARP bolts, TRW 11.5-1's)
- PORTED '69 215 heads, 2.19/1.88, flow right at 325 @ 700
- Holley Strip Dom intake, or 454-O (as per Marks recommendations)
- Bullit SR .710/.710, 264/274 on 106Cl 108 LS
- reworked Holley 830
Now I'm not saying this is one of those REAL 700Hp 396/402's, just wondering what you guys think this made and why from the info we were given. Is it a real 630Hp engine???
