early turbo 400 bolt to edelbrock crate motor?

does anyone know if this will work? my buddy needs to know. he was positive i could tell him and i dont have a clue. they didnt have "edelbrock crate motors" back in the day. i am assuming it will bolt right up, i think think the bolt pattern has been the same for small blocks and big blocks from the 265 up till now. any issues with flywheel/flexplate fit? how about the starter? thanks.

Bolt pattern is the same for Chevy engines.

Starter, you have the 153 and 168 tooth ring gears, and the blocks and starters usually have accomodations to fit either one, there ARE some exceptions on the older blocks. Easiest way to tell, on the starter mounting pad, if there are 2 holes drilled and tapped for the starter, it's a 168 tooth only, 3 holes- 153 OR 168.

If the engine is an 85 or older it has the 2 piece rear main seal, and the 86 and up has the 1-piece seal, the flexplates and flywheels ARE different for these two engine years, they have a different bolt pattern, and the center hole is different, the newer ones have a balance weight- whereas the 85 and older were neutrally balanced, they won't interchange.
