GM HEI

I dont recal what those 3 were exactily. They were all for a brand new chevy stroker 383. The motor was drop shipped through summit (383 crate) with a bad distributer.

(Would not keep time)

Two more were sent out (no charge) and both units were dead on arival.

After that I installed a probillet and digital 6al and the car went out the door.

The vendor was VERY good about the entire thing and I still buy crate engine through them today.
