Hey all ive been creepin the msg board for sum time and have got a lot of excellent info from you all.... I have an 85 buick regal with original paint, excellent body and frame, i put a 200 4r tranny in it with a trans go shift kit in it , 373 rear end gears from a 00 s 10 and a posi unit from a monte carlo ss, still the 10 bolt... i also got a olds cutlass off some one and it had a rebuilt 1982 350 with 305 heads and a rv cam in it. I have installed this into my buick. My question is what can i do to upgrade.... ? When i installed the engine i used my original intake and carb from my 305 in order to keep all the pollution **** intact. I have 275 60 15s on it and if i put her in 2nd and brake stand it then let off the brake in 2 nd at about 4000 rpm it will put a good strip of rubber down. It seems to fall on its face around 4200 rpm.... now from what ive found on line its around 10 to 1 compression .? Im wondering if the vortec heads with the ghetto grind and home port job with a aftermarket intake with egr friggn plumbing and a nice 650 carb is a good upgrade ? because i think it will be trading off the compression for better and more efficient flow ..... im a licenced autoservice tech and this older school stuff is giving my brain a work out. Also wondering if maybe the quadra bog just needs tuned butter on this 350 set up as its off the 305 ????
