Why are these #'s critical for a good torque build?

In this, episode 71, DV and crew chief Mervin Bonnet, reveal certain easily attainable combinations of parts can generate a stronger torques curve than others. This increased torque potential can amount to a sizable increase in lbs-ft per cube so it has the same effect as making your engine feel much bigger than it really is. Since all the moves described come about through increased efficiency you can expect greater fuel mileage as a plus.

Thank you for passing on your knowledge! Absolutely wonderful, Godspeed.

Thankyou for sharing that mr vizard.your knowledge and experience with engine's is immeasurable.peace

Thanks again David!! Loved Mervin’s spiral lock tip! The strike and compression talk was excellent!! It gave me a batter understanding of how torque is produced

Anybody that worked for this man should pay him.

Dave I’m into early vw air cooled engines and would you think that 10.5 compression applies, as the general thinking is 8 to 1, saying to keep heat down and so it doesn’t knock . Thank you I enjoy your videos and have one of your books too😊

DV, Would you say the total friction (not just the negative impact of the side loading in the bore)of the engine; the valvetrain/ bearings etc., is the secondary player that compliments the strokers combustion and compression advantage for tq per cube? My informal experience of observing years of Engine Masters competitions, appear to favor tq production of engines approaching or at 400 cubic inches. Additionally, having guest speakers from your career is great. Thank you Mr. Mervyn Bonnet for your time! v/r wh

Mr. Vizard, It appears the 400 cu. in. small block is the red headed stepchild in builds. I don't understand why, people are so willing to give up cubic inches of the 400 to grind and machine the 350 block to gain 30 more cubic inches. What are your thoughts on this.

[VLenny]

S54B32 has very long stroke and short rod, revs to 8000 rpm and has one of the highest torque per qube, from factory.

[jimclarke]

Excellent information, takes the guesswork and huge expense out, if installing wrong parts

A 496 stroker project isn't much more then a 383. And has more potential for future upgrades.

I actually lost sound with Mervin came on then when it went back to David I had sound?

[witnesszer]

david ive always wondered if you ever blown up any engines

[joeinmi]

That's why 5.3 ls' run so hard for their size.

[pmd]

Too much low end torque will break the tires free at low rpms.

This idea of choosing the perfect cam isn't realistic as many of us can't afford to buy and test 5 cams to find the best one.

A 400 will put out about 40 hp from a 350
