408 Sbc ?
Looking at a 408 stroker. I know the 350 block has to be modded to accept a larger stroke and care must be utilized not to hit the water jackets. Obviously a 408 must be machined more to accept the 4.00 stroke than the 3.75 stroke on a 383. If built & dyno'd by a competant machine shop, is there much danger of popping a water jacket later? I understand that over heating any engine leads to bad results.

Yup they do it with the LSxx blocks all the time, 4 inch crank, ain't too popular with first gereration small blocks, I would talk to a machine shop that has done one or two before

I've seen two of those 408's 4 inch strokers and 4.030 bore. In our old style 4 bolt blocks. Both of them used epoxy to fill the lower water jacket area. The 3.875's that I built didn't require that. You end up with about 396 ci.
For just 12 more ci I didn't think that it was worth it.
I'm using a 4 inch stroker in my Motown block. But they are made to take on 4.125 without clearancing anything and 4.250 is just a little grinding.

T and L engines regularly builds 408s from Gen 1 SBC. 4" stoke in a .030 over 350=408. Just wondered if they were streching it too much.

I thinks its all forged internals with hp dependent on the cam you choose, but it claims 450-550 hp, all for only $4350

T and L built my 383 stroker which I am very happy with, they weren't building the 408's last February 05 otherwise I would have probably gotten one. Lloyd McLeary the owner has been bulidng nascar engines for a long time, he was actually very heavy into Nascar in the mid to late 90's then the Yates, Rousch, Hendrick came along and took all the engine business. He is now getting heavy into the aftermarket engine building. Last year I know T and L was still building engines for Derrick Cope and one other Busch driver.
Their facility near CharlotteN.C. is top notch and my son and I were there when the 383 was dynoed. We were actually lucky enough to have Lloyd build our engine personally and he reworked the AFR195 heads to address the poor oil return and valve seals.
I am confident he will stand behind whatever he builds, he is very much into shaking the engines down on his dyno before he ships them out the door.
Here's a pic of our 383 being dynoed at T and L:

It's dependant on the cam you choose. JUst shows how much difference a cam change makes when everything is the same.

b71vette,
Thanks for the picture. On paper this looks like a class outfit and it's good to know that you were a satisfied customer. I was going to buy a short block & build the top end, but I'm seriously thinking about the 408.
