Carlo,

First: it will be a shame to remove the hot looking motor from the steel flared car. A stock motor wouldn't look right in that engine bay.

Second: Will that motor qualify for the class rules you'll be racing under? In particular I'm wondering if the rules will allow the CHI heads or will they require stock heads.

Third: I wonder if that motor is really built to race engine spec? A race engine needs to be durable and built to run at high rpm so it can pull any long straight aways lap after lap without damage. For instance:

Are the pistons round skirt endurance pistons or slipper skirt style pistons.

Does the motor use floating wrist pins?

Have the cylinders been indexed, the crank saddles align honed, the decks leveled?

Is the crank internally balanced or externally balanced?

Has the reciprocating assembly been dynamically balanced?

Were lifter bore bushings & cam bearing restrictors installed?

What's the hot oil pressure?

Are the valves made of light metals? i.e. Titanium intake valves, hollow stem stainless exhaust valves?

What brand/quality of harmonic dampener has been installed?

Is that solid roller camshaft designed for road racing/endurance racing? What are the spring pressures seated & over the nose?

What's the OD & wall thickness of the push rods?

I'm not against combining a steel crank with the thinwall production engine block, but in true race applications the oem iron crankshaft lessens the risk of cracking the block.
