Anything that can be done to keep the TQ curve from going down so fast? Seems like after 5100 it just nose dives off the sheet. Maybe a wider LSA?
Just curious.
I think the motor is a nice one. I would be happy with that.

Keep in mind this engine, with this cam , as dynoed shows a healthy low mid range torque curve. It is well matched if you are just going to use 3.73 gears.ClassicRob wrote: ↑Tue May 18, 2021 6:21 pm Anything that can be done to keep the TQ curve from going down so fast?

Adding more duration will increase top end power and extend top rpm it will trade off low speed torque . It will want big gears. More top end but not as "streetable".

I agree, I should have had you pick the cam! I built another engine with a factory stock cam 350 HP 396 cam just to see what would happen, I will probably post that up, it was interesting.

Any more movement towards posting this one up..? Im very intetested

This link popped up in another thread so I'll answer your question now.vortecpro wrote: ↑Wed May 05, 2021 8:33 pmskinny z wrote: ↑Wed May 05, 2021 11:11 amIt may be a known element for some but for me, getting to know how to get a 2-bolt block and factory cast crank to survive the RPM I figure needed to pull this off is the real deal here.vortecpro wrote: ↑Sat May 01, 2021 11:22 pm Building a 4.060 X 3.480 360 inch SBC, 618 2 bolt block, factory 5.7 rods, cast factory crank, flattop pistons, 2.02 fuelie heads, solid flat tappett cam, .515 lift @ valve, 242 @ .050, 108, installed @ 104. Air gap intake, Milodon Chevy II oil pan. Dyno test Monday. Looking for a 10 sec Chevy II.
I've personally made hundreds of passes on a stock 70's era 350 with factory rods (with ARP hardware) along with the original cast crank but maximum engine RPM was 6000. Maybe 6500. Might have been a 400 HP lump given a 106 trap speed and a 3700 lb all street car.
My question is: how is 106 MPH 400 HP @ 3700 pounds?
Because it doesn't have the correct gearing or converter.
