it's a 318 built like a 340 flat tops 10:1 floating rods steel crank ..cam is a complete cam ground for nitrous and thru the 1.6 full rollers it's .528 lift .. I ported the 915 heads and put the last set of trw valves i had with new springs retainers keepers ect . had a m1 intake on it but the tci converter was too tight so until I can get the 3500 in I swipped to a airgap .727 with upgrades and shift kit installed .8.25 rear with new posi unit and 3.91 gears .. car came with a 1/4 stick i didn't like so pulled it and bought a complete E body slapstick and welded in ..only have about 150 miles on it so far ..painting took forever it seemed with all the coats of clear and pearl.
