RE: stroked 390.... |

http://www.rosspistons.com/bbford1.html to get Ross pistons they have them for the 410, or call Ford Power Parts at (562)921-5300 I think they have some in stock too
This is a copy of a post I made that shows what I was thinking of running for my 410: "I'm curious if anyone feels like running these specs through a computer dyno if they want to. PART # 33-781-8 GRIND NUMBER: FB 288R-10 ENGINE: FORD 390 - 428 INTAKE EXHAUST VALVE ADJUSTMENT .020 .020 GROSS VALVE LIFT .633 .633 .015 TAPPET LIFT 288 288 VALVE TIMING OPEN CLOSE AT .015 INT 38 BTDC 70 ABDC EXH 78 BBDC 30 ATDC THESE SPECS ARE FOR CAM INSTALLED AT 106 INTAKE CENTER LINE INTAKE EXHAUST DURATION AT .050 244 244 LOBE LIFT .3666 .3666 LOBE SEPARATION 110
This would be for a 410 4.08 bore (.030 over) 3.98 stroke, Edelbrock heads (flow #'s for #6006 .100-88/64 .200-153/113 .300-195/148 .400-233/171 .500-265/183 .600-270/200) and Performer RPM intake, 10:1 compression with 1.625" primary headers 31 inch long if I remember my header specs right and dual 3" exhaust. The carb would probably be a 750 Edelbrock or 735-750 Holley The cam is a solid roller and I'm curious how good it would perform in a 410"
The computer dyno responses I got were: " RPM'S HP TQ
2000 175 459 2500 224 471 3000 276 483 3500 338 506 4000 397 520 4500 447 522 5000 487 512 5500 508 485 6000 504 441 6500 483 390 7000 450 338 7500 415 290 8000 364 239
+/- 7% and...

"
I had one person vouch for each of those replies, one person had a 428 with CJ heads and his MPH in the 1/4 said 530hp
I think the Tri-power will hinder the top end as I have heard they run out of gusto at 5500-6000RPM but be good for the bottom end, what crane roller cam are you using? I'm thinking of switching to a hydraulic roller since I will drive it very often. |
