torque/HP estimate? 351w roller block

Just keep in mind that those E-brocks start to go flat after around .550 lift and adding more can force them to go turbulent and actually start going backwards.

IMO, that cam in a 351 will likely put you up around 370 horse and near similar torque figures.

 

Well she is together and went with shorty headers due to fitment issues, I was really surprised at the torque down low. I figured it would be a dog below 3000. I used a calculator for cranking compression and it was way off so don't trust them. The calculator estimated that I had 131 lbs. and I tested it just for fun even though rings aren't seated yet I Got 155 lbs. on the 2 that I tested im guessing that puts my dynamic ratio up in the 7.5 to 8:1 thank goodness. Later all and God bless

 

The rods are your weak link. Save yourself some trouble and change to a better rod before you start to drag race it. The stock crank will take a lot but we've broken a lot of those rods in years past. The truck rod is marginally better than a car rod (football bolt head vs square cut for bolt head) but still not that great. A cheap set of H-beams with good bolts will save your short block.

I don't think I will have to worry about rods, will never go past 6000, and most likely will make 5500 my rev limit. I just cant believe the initial this motor wants to run at on 91 octane it likes 20 BTDC best for a good strong idle and no hesitation, but I am gonna stick with 15* till I get exhaust on it which will be completed in 2 days and then ill be able to hear and pinging or detonation under load. Anyone else get best performance at 20 initial and 40 total at 3000 rpms?

 

"will never go past 6000, and most likely will make 5500 my rev limit."

Sure...I have heard that before...

Sorry...forgot how to use the quote function. It wanted to quote entire post...
