I did'nt start out to build a 12 to 1 on 93 street engine it occured due to a matter of circumstances. A friend asked me if i wanted to buy a set of Brodix 11x heads ported,polished,and bench flowed by Indy Cylinder Heads, traded for a 406 block with Howards splayed main caps. When the heads came in they were bolted to the 358ci. He suggested rather than seperate them i just buy the bottom end for 1500.00 the bottom end is 71 block that has been squared,decked,offset bored,line bored to clean with a Scat light weight crank with mallory,Eagle 6" H-beam rods and JE dome pistons he then threw in a Reed solid roller 262/267 @50 618/625 lift. At this point i owed him 1500.00 when he reminded me i had previously offered to sell himm my 383 short block for 1000.00 that said i now owed him 500.00 an hour later he offered to call it even if i left my Hyd. roller and Lunati Hyd.roller lifters done deal. At this point i went out and bought a set of Crower solid rollers and a Edelbrock Pro-Flow2 fuel inj unit and figure i'll run it and see how it works out. I wanted to look into having the pistons fly cut but no can do they have the same profile on the bottom as the top. The cam was designed to bleed off cylinder pressue and if it does'nt work it's not like i have a ton of money in it. I was originally building a 415 with a Vortex ysi supercharger this is just a little side trip.
