You can drive on them fine, my 408 will however easily get rubber with Cooper Cobras into 4th gear lol. All at the discretion of your right foot.Silly question, when you have a stroker like a 416, are 275/60r15 bf Goodrich radial ta's ok for driving or do you need something that sticks to the road better?
I have a 4.04 x 3.58=367 and with Eddies and a 230* cam, and it's a streeter's dream at 10.9Scr with the KB 107s....... I couldn't wish for more. I'm actually thinking a lil less would be ok, to get back a lil fuel mileage. I'm thinking of a tighter LSA is all, and shedding a lil exhaust duration.who have built a 340 / 372 stroker
Scat offer cast and forged crank rotating assemblies.
how do you like this combination?

AJ, back down 1 cam size, 224@050 and port the heads. Find a high lift cam and use 1.6 rockers. A 108 is what your looking for on the cam. The engine is large enough for it. You should have a new peak around 6K.I have a 4.04 x 3.58=367 and with Eddies and a 230* cam, and it's a streeter's dream at 10.9Scr with the KB 107s....... I couldn't wish for more.

Mine is a cast-crank 360 base. My butt-dyno thinks peak power is about 5200, but I rev her to 7000...... because I can,lol.

Because it is a waste of fuel to make less HP & Tq @ that rpm while adding undue stress to the engine.It's a streeter and spins to waaaay past 65 mph so what do I care....... even at 7000/7200,lol.
Seems AJ just wants to hear that engine scream... no matter the waste of fuel... and as he stated his little motor took that for over 100K now.If you want to stress your engine out that way well, I see a rebuild in the future ........ that wasn’t needed.
..this combination was not easy to come by when the 4" kits were everywhere.
..but now Scat offer about five 340 / 372 combinations staring around $1000 w hyper
pistons or $1200 balanced.
thinking 372 might be a better "all round" engine than the 4" torque monsters.
your thoughts?
It seems a lot of people here have the misconception that engines with 4" and bigger cranks won't or don't like to rev or that they are slow to rev.
My 408 was very quick, it was fastest shifting at 6400 because it was running out of head flow, it had the cam and everything else was there it was just running out of air.
Better all around....no, sorry its not....but if it is what you want then go for it, its your motor, build it however you like.
Just some thoughts and all are arguable....
more ecomomical to build?
quicker revving and accelerating with stock heads?
better mileage ?
more stabil pistons?
less piston speed for the same rpm?
much less long term wear?
better bore to stroke ratio?
much better balanced package for the street in a light car where big torque is not necessary?
you can buy a 3.58 stroke 340 main crank....use stock rods...and KB 107 with a 4.07 bore if you want a budget one
If you don't want it let me know. If price is right I'm interested for sure.That is good to know, I have a buddy that lives up the street from me that has been begging me to take a 3.58, 340 main forged crank from him, it is a new in the box, Mopar Performance or Direct Connection one from the early 80's.
I may just go up there tomorrow and pick it up.
He tried to give it to me last time I was up there helping him.
I will go up and see him in a few days, like I said he wanted to give it too me, but I would feel bad, he is disabled, retired but still building cool cars.If you don't want it let me know. If price is right I'm interested for sure.
Oh yes I had no expectation of free. Let me know what it is and what he would want and we can go from there. Let's continue this with PM.I will go up and see him in a few days, like I said he wanted to give it too me, but I would feel bad, he is disabled, retired but still building cool cars.
I would not feel right unless I paid him a reasonable price for it.
He did say it was his spare crank, from when he was racing his duster back in the late 70's to early 80's, he had that old duster in the mid to low 6's in the 1/8 mile running 318 blocks, W-2 heads and nitrous.
Now he is just putting around in a healthy big block chevy powered 32 ford 5 window.
