Update...ran the numbers on the new block and new heads. 3970010 block...69-79 185-370 hp 2 or 4 bolt mains. Mine are 4 and I haven't dynoed I will after new heads are installed this weekend. 14022601....80-86 305 heads I) 1.84 E) 1.501..(update) took em to the machine shop to have em resurfaced...revealed a crack on one...supposively on the final pass...So I paid $100 for heads, $18 for a couple valves, $90 to resurface, and it took me 4 hrs to clean surface rust and renew seals and shit just to find out I can't use em! I'm telling ya..this thing won't let up..I've never had so much trouble with a car...but it's almost ALL brand new or within 6 months old now.More new updates. I got Brand new Summit Racing .030 flat top pistons, New Clevite 77 bearings, Melling hardened oil pump shaft, Summit Racing High Vol Std PSI pump, Waterpump, Fel-pro full gasket set, Moly Rings, and some new bolts and misc. things. I am gonna be getting the Cam and lifters, steel roller tip rockers, second head or new heads, and putting this thing back together in June...THANK GOD..it sux being a Auto tech that can't even afford to put parts into his own ride...but that's what happens when you got 3 kids and another one due in December! :) Update.. Got the second head...in pretty good shape...just gota clean it up a bit. Latest update. 3/1/12The flat top pistons I got were for a 350..my dumbluck, so I got the 383 pistons for my bday but they're not flat tops..all good though cuz I wanna boost it later anyway so the dish will help lower compression. Also went with some 350 heads instead of 305s. The bottom end is all together and the cam is degreed. However, in the move I lost the damn Cam Thrust Bearing. So now it needs that to be able to clearance it and put the rest of the thing together. Always something with this damn car. The bearings only $25 then it's gonna need a battery to so there you have it. This is the most up to date I've got at this point. Maybe soon she'll be running again. I'm hoping before spring! My bro's starting a car club and wants me in it so I gotta get a move on it before show and track season really kicks off!!
