305 to 350

[RenaudB]

hey i only have a 305 and want to change for 350... my transmission is from a buick regal 81 and my rear end from a 91 s-10 4.3... still these will fit a 350 or should i change it too?

[tracker]

same same, it will all switch over.

the only thing different in a 305 and 350 is the piston diameter so anything you want to swap, will swap.

Go for it! It will swap right over. The outside of the blocks / externalls are the same. The inside is a little differnt. the bore and stroke aren\'t the same, Just like the horsepower isn\'t the same.



Space.

hey space. I thought the stroke was the same?

[spacecadet]

Sorry... your right. stroke is the same. I was think 400 vs 350.



305 = 3.740\" x 3.48\" (Gen.I, 5.7\" rod)

350 = 4.000\" x 3.48\" (Gen.I, 5.7\" rod)

350 = 4.000\" x 3.48\" (\'96-\'01, Gen. I, Vortec, 5.7\" rod)

383 = 4.000\" x 3.80\" (\'00, \"HT 383\", Gen.I truck crate motor, 5.7\" rod)

400 = 4.125\" x 3.75\" (Gen.I, 5.565\" rod)



350 = 3.900\" x 3.66\" (\'89-\'95, \"LT5\", in \"ZR1\" Corvette 32-valve DOHC, 5.74\" rod)
