Has anyone out there clearanced a SBC 350 for a 4 in stroke? With a 4" stroke and bore this would seem to be a real torque machine.

I have not clearanced or even had one but I am getting a custom built crate motor from T&L engines. It has a 4" stroke. Its 408", dart heads and a hyd roller and it makes 520lbs tq. Its like 400lbs at 2500 rpms.

Yea. I have seen the crate motor add. I think you could build a real thumper with that stroke. I just got a free block, and am going to try doing the clearance myself. Just wondering if anyone else has tried it.

yes it is common motor. I have built a few 3.875's which is 396 ci. They just kick the 383's butt's

I was running some numbers on DD2000 last night. With a set of afr heads and solid roller in the range of 240/245 .570 it was pushing 550 hp @ 6000 with peak torque coming at 4500.

I know you have done a few 396s, but it would sure be nice to talk with someone who has built the 408.

I have not built one but I have a T&L 408. There's lots of torque all through the range. Its lots of fun to drive.

do you use this site for parts or reference gkull?

I have a set of srp forged pistons with less than 50 miles on them. So I will try to piece together the bottom end. This project is going to take a while, by parts as I can afford and the machine work. I've found a scat forged crank for 459.00, but I'm still in the planning stage.

gkull

I've bought 5-6 stroker rotating kits from Flat Lander racing and one set of heads. They have always been good to me.

another company I used for my first complete 383 was Martel Brothers.

The better machine shops have a fixture for clearancing blocks.

I have seen pics of templates for the 383 several years ago, don't remember where. But never for the 408

I am albout to clearance a OEM 400ci block for a 4 inch crank (427ci ), so I would be interested to hear if anyone has actually done this too

Ironcross

Nothing new, 4X4 Small block chevies have been around since shortly after the 265 V8 came out. Which is nearly 50 years of actual 4X4`s usage. They had to figure out what rod to use. 283`s were only slightly better to use

I recall an eng with the same stroke as bore has the widest/broadest pwr band. Man this is great idea, but how do you clearance the block? Anyone got good links for this?

And the price is right now too - not hardly and more $$ than a stock stroke. SCAT cranks use the 6" rods too - man the ring pack gott'a be tight.
