So I already bought it so it's kind of too late, but I need some opinions. So I bought this 406 Chevy small block, it has splayed 4 bolt billet main caps, eagle forged crank and H beam rods, mahle forged pistons, Brodix IK200 aluminum heads, harland sharp 1.6:1 roller rockers Brodix SP1 single plane intake manifold, holley 850 DP carb, and an unknown but supposedly pretty gnarly cam matching the intake and heads. Supposedly it's 10.5:1 compression and only had about 2,000 street driven miles on it before the car it was in (C3 Corvette) was crashed and totalled a couple years ago and the seller decided not to fix the car, pulled the drivetrain and it has been in his garage since.
So questions, it has a basic looking internal balance style harmonic balancer, so does that mean I can I use any typical SBC flexplate? Or do I need a weighted one for a 400. I am 99% sure it's internally balanced those forged 400 cranks usually are and the neutral balance harmonic balancer sort of backs that up. It was in front of a manual so I need a flexplate.
How much power do you think that setup makes, I'm guessing around 500... Should I swap for a milder cam and dual plane intake for a more streetable engine?
Also this i really don't know, I think it's a 6 inch rod build... Do they live relatively long? Those ring support things that protrude into the wrist pin hole makes me a little nervous, but a ton of guys are running strokers like that, so it must be fine... I personally would have built it with 5.7 inch rods to keep solid ring lands all around the piston, but you can't always get what you want.
Final question, will it run fine with an OEM stock HEI distributor or should I get an MSD or Mallory/Accel or whatever? It comes with everything but the distributor and flexplate.
I pulled the valve covers and oil pan and it looks brand new inside. Fingers crossed the seller is honest and he really did destroy the car it was in, and didn't pull the engine because it's hurt.
