I believe the torque is figured on the bolt size, not the material. you are using steel bolts ,therefore the torque for an intake bolt on a sm. block is 20 ft. lbs.
Iron Intake to Iron Heads - 40ft lbs Aluminum Intake - 25ft lbs
i retorqued my Chevrolet heads to 90 ft. lbs. but i also found if you use the specific torque pattern the gaskets will seat better....i don't torque my intake boltsAnswer65 lb.ft.
With iron heads, the stock spec for iron intakes of 30ft-lb should do. If you are going into aluminum heads, you do not want to go very tight, maybe 20ft-lb or so. AFR recommends just making them "snug" when installing an intake and exhaust headers on their aluminum small block heads.
for a Chevy 350 enginge its 25 to 30 ft lbs. cast iron heads.
A 350 SBC with aluminum heads and intake would weigh approximately 450-500 lbs. Adding carburetor, headers, alternator, water pump, and other accessories would increase the weight to around 500-550 lbs.
NO.
With cast iron heads it is 30 lb/ft. Tighten in a criss cross pattern.
About 550 pounds. This would assume aluminum heads and intake, and a powerglide. And it would be closer to 575 with fluids.
The 3.1 L V-6 engine in your Chevy Corsica Has Aluminum Heads
No. Not without switching the cylinder heads. I think it was 89, Chevy came out with the 1st generation Vortec heads, which require a different intake.
No such thing as a DE-TORQUE pattern.Just remove the bolts from the heads from front to back.
Some have aluminum engine blocks and/or cylinder heads, many of the sensors, intake manifolds
