OK guys...after bothering the heck out of some of you about how to build up the 350 in my sig, I finally have all parts gathered with the exception of the exhaust which is totally stock. I believe my 77 LM-1 stock 350 is rated at 170 HP. In the next few weeks I'l be adding; Ported and polished L98 083 heads with stock size valves with 30* back cut, 1.5 roller rockers, and springs to match the cam. The cam is the comp 268H. Edelbrock performer manifold with EGR. New roller timing chain. I will be using my stock cc Q-jet for the time being, as well as the stock exhaust system. Can any of you guys estimate my HP increase after putting this stuff on ??? Will I see a significant power improvement ??? This was all I could afford for the time being. Will add Edelbrock TES headers and catback this fall. Appreciate any comments or opinions you guys have about this. Thanks !!!!
