which cam

[1986]

yes it has a 700r4. what should one expect to pay for a torque converter like the one you mentioned? will the 260 be fine with the stock coveter.
im not even sure what a higher stall coverter does, or what lock-up and non-lockup means.

yes im just using the 4.3 tb and injetors bolts right in but the intake needs to be bored like 923.46v mentioned.

i dont know to much about cam numbers, 260, 272 are duration #s right. what are the pros and cons of both? why is the 272 too agressive for DD.

both the H260-2 and the H272-2 are Crane cams, the 272 has a bit more valve overlap which causes a nice lopey idle and lower than normal idle vacuum which can effect the power assist brakes. It's not extreme by any means and you certainly could daily drive it with a bumped up idle speed (around 950-1050 RPM)

If you have an Auto tranny you'll want to pick a different stall converter, something around 2500 should work.. if not the fact that you'll have to bump up the idle for the 272 will cause it to lurch at stoplights and can damage the tranny over time. If you have a 5 speed then you'll be fine.

If using a 4.3 tb you need to port or bore the intake since the tb will have a bigger bore. If tearing engine down what about dohc 3.4 pistons for an increase of compression.

Yea the 272 does not have the Idle quality of the 260 but it will make more top end power. John over on S-series used 272 in his 3.1L build and he really liked it.

Go with either the 260 or 272 cam just decide what suits your needs and application.

[Superdave]

the 272 is a bit agressive for a daily driver, the H260-2 from Crane is a very nice cam for a DD and easy to tune for.

crane 272. good power, great economy and sounds like a lumpy cam. easy fo tuning

how are going about the 4.3 setup? just using the 4.3 tb with injector? most of the 90 degree v6 parts are not interchangable. are you fabricating?

im rebuilding a 3.4 off a camaro, its going in to my 86 s10. the only performance mods im thinking of doing is a port & polish job on the heads maybe mil them a bit for a small compression bump. im going to be using a 4.3 TBI setup, can someone help pick a cam that will be street freindly with a nice power incresse.and tell me which ones to stay way from
