I think this is true. I was always under the assumption that the stall speed matched to the rpm where the torque peaked (or thereabouts) would give the greatest acceleration. But then I read an article in which an engine builder said that a real race car never operates down at peak torque. It...

My PTC 9.5 flashes to 3500 and gets me in the powerband instantly. No waiting around until 30 mph. Drives fine with 3.23s. The low gear sets for 904 are fairly cheap and available . Low gear sets for 727 are pricey. My opinion: Since you haven't built the engine yet, spend the money on a...

I couldn't really read your cam card. The few numbers I could make me think it's an XE268. Maybe a few more details? engine size,etc? Is the carb new? From 1984 to 2019, I drove exclusively 60s-70s cars with carbs as daily drivers , all kinds of weather . But I'm a weirdo.

We have AJ's math and we have actual drag strip times from 318willrun's lo comp 360 duster. I'm not gonna go through old posts to refresh my memory, but I believe he went 13.90s with stock converter and 2.45s. 12.80s with SM heads , 2800 stall and 3.23s. And we have Holdeners dyno results...

Ended in 71, I think . My 71 RR had it ,my 72 Duster didn't.

cam?

This is how I'm going to do it if I end up doing a magnum swap for my Duster. I want it to look as much like an LA as possible. You may already know this, but the 5.9 magnum has a balance that is different than the LA 360. Several companies sell balancers with bolt on weights to match the...

On an episode of Roadkill Garage, they did a 5.9 swap with the factory acc drive into a Duster and had to move (chop up ? , I can't remember) the battery tray and use a small battery to clear the ps pump.

I would make sure the cooler isn't plugged first

In-Head Piston Cutters Might be cheaper to make a tool. Or the sleazy way, mark it and use a die grinder. What is this wild circle track cam? I don't think I would take those cast pistons much past 6000 rpm. If the cam likes lotsa rpm, you may be better off with something smaller.

Cam , headers and 4v ought to get 250+ pretty easy. Good enough to get well into the 14s with stock converter and 3 series gears in an Abody

:lol:

Pretty sure I've heard you diss a 360 because it's a 360.

416 is perfect for A body . BB is perfect for B body. :p
