Micheal Trew told me about this group while we were conversing via email about my truck motor build . The motor is a 305 "H" motor in a
1986 GMC 1500 LWB pickup with a TH700R4 and 2.73:1 gears . The motor mods include a .030"over bore with flattop pistons (anticipate about 9.5:1 or so c/r) , stage 3 cam (ELGIN E-922-P) small/long tube headers , Edelbrock Performer EPS manifold with a Holley
750 CFM vac secondary carb . I have the HP heads with 55 cc chambers . This motor is rated 165 HP stock with 9:1 compression . I'm hoping that between rippin' off all the smog gear and the mods I'll make around 250 HP - though that may be optimistic . The exhaust system will be 2" dual with Thrush Hush mufflers . I don't need or want to advertise . The other major change will be replacing those 2.73 gears with a set of 3.42's . We live on the southern edge of the Ozark Plateau (north central Arkansas) and there a 2 things the roads here ain't . That's straight and flat ! Great roads for bikes (ask me about my Harleys) but them flatland gears ain't cuttin' it . The only other change I plan - for now - is a shift kit in the trans . I need to do some research on that one , I don't usually mess with automatic transmissions . BTW , A/T's are about the only thing I don't usually work on , I maintain all our cars and bikes . And I have a pretty complete hobby machine shop ...
