Jim assured me the 781s would be the way to go after his partner and legendary Blown Fuel Altered pilot, Mikio Yoshioka, did his magic to them. He drove the Stone T altered back in the 60s. NEAT STUFF!
Eagle rotating assembly and Mahle pistons make up the rotating assembly. The squeeze came out to 9.8:1. Valve timing is controlled with a Comp roller with .615" lift on intake and exhaust 240*@.050 intake and 250* @.050 exhaust on 112LSA. The old school Torker was a nice eBay find and was ported and port matched to the 781 heads. MSD dizzy and coil for the ignition and an 850 DP Holley tops it off.
Engine was ran on a stand but not dynoed. We will strap it to the chassis dyno at a later date.  |
You are gonna be happy with that combo, it makes for a great street engine.
I did a very similar build, except 12.5:1, NOS ZL-1 9180 cam and with the Angelucci ported 781's it RPM's like a 2-stroke weedwacker and makes power from idle to redline.
