Re: The GSFMech Build
Yeah sure did, I made a lot of changes. I wanted a little more thump even though it ran good before and was impossible to hook up. I was running L2465 Speed Pro pistons before and 781’s but they were stock except for a 3 angle valve job and had a lot milder cam. I machined the heads for 2.19 and 1.88 SS valves with the cut down stems, and machined them for PC seals and comp cams dual springs and did a real nice bowl porting and 3 angle seat job. Factory steel crank, 3/8” truck rods and I had aquired a vintage set of L2349 TRW closed chamber 30 over pistons that I used this time, this boosted the compression a little. With a set of steel shim gaskets it came out to 10.3:1. I also had it balanced. I added an old style LS-7 corvette trap door oil pan, windage tray and oil pump (Chevy still carries this stuff). Lunati Voodoo cam, GM long slot rockers, performer RPM intake, I modified my 850 double pumper for 4-hole idle to try and get some of the hit out of the cam with the AC on, Mallory coil and pertronix ignition, big tube full length Hooker Chevelle headers. I also went with a TCI breakaway converter. It runs real good but it took a few months tinkering to get the advance curve and spark plug heat range right. It was a ping monster for awhile but it’s just about sorted out. I still need to play with the jetting a little more.
Thanks for all the compliments ya’ll
