i was thinking of finding an engine for a 510. but i dont know what to go for. i have a z24s bllock from a 720 and i was wondering if i should build a a hybrid motor and tranny set up by adding a l20 head (or peanut head) adn other components, flat top z pistons, z flywheel, z bell housing, clutch, and 5 speed tranny, or if i should just put in a z24s motor and manual tranny, or just find an l20 with a manual tranny. i think making a hybrid wil be lot of work but worth it in the end. thanks.

Well, first off, a L20 motor isn't bad. Is drove a 510 with a L20, and man, its some fun hp. If u want to go bigger though, go with the hybrid.

yea i was intending on buiulding the hybrid motor and tranny setup then just find a car to put it in or just sell it to someone who actually has a 510.
