I'm getting a lot of mixed answers on stroking out 2 bolt mains. So any experiences with this would help.

Mainly Im worrying about structural integrity of the motor. Last thing I want is to have 3-4 grand fall apart. So 350 2bolt stroke it out to 383
Or not? Older virgin block. Getting it for free along with 350 heads and no I do not have casting numbers with me.

And my local machine shop isn't open to ask. How much does boil/ crack checking cost~. And machining it needs the works.

O and I want this motor to put out a least 400hp 400tq

It'll be fine. It also won't cost you 3-4 grand for 400/400.

Machining costs are different depending on where you take it, shouldn't be more than a few hundred though.

2 bolt main will easily handle what you want it for.

Alright , I thought it would be OK but I hear a lot of people saying for a stroker motor go 4bolt

its the popular thing to say. unless you are going for serious hp that 2 bolt will be fine. you can get a kit to make it a 4 bolt but theres no reason to really

Whats a good brand stroker kit with crank. Scat?

Scats or eagles aren't bad for lower budget stuff... I can't remember which but I had an issue with a scat or eagle crank... Went to drop it in and it hit the small hump on the inside of the oil pan casting. Only had an issue once and I have built hundreds of engines with them. About 2 bolt mains... I have yet to see a broken main cap and I build a lot of oval track and drag motors. I have an .100 over stroked 350 with a .702/.710 lift cam with 14:1 compression and it's a 2 bolt main. I try to blow that fucker up and it won't pop

Machining wise you could technically do it yourself it's not a big deal. I have templates made for every block for stroker kits. I just bolt in the template with the main cap and score it out and just grind it. As i said before once I had an issue with the crank hitting elsewhere but only happened once because it looked like they missed a step in machining the crank itself. It normally only consists of grinding the bottom on the cylinders and boring/ hoaning it after to get rid of any edges that may score the piston. a 383 is a .030 anyway.
