350 chevy with aluminum heads and intake carb and headers weigh
For one with an iron intake and heads, approximately 650 lbs. An aluminum intake will reduce that by about 20 lbs, and aluminum heads by about 70 lbs.

when their is two culturals that bump heads because of their differences.
Quite well in high rpm applications.
Depends on a few things such as if you are using aluminum heads & intake and headers, or the factory iron parts. If it is all factory, with the exhaust manifolds on it about 620-640 lbs. Substituting aluminum heads, intake, and headers saves about 75-80lbs.
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.
I think a hotter cam , aluminum heads and intake probably headers maybe that tougher block I've heard about . Its a much faster car .
Iron Intake to Iron Heads - 40ft lbs Aluminum Intake - 25ft lbs
Some have aluminum engine blocks and/or cylinder heads, many of the sensors, intake manifolds
carb, cam, intake, headers, heads, msd igntion, or a 350
Yes , you would have to unbolt the headers from the cylinder heads
202 refers to the intake valve size, as in 2.02 inches, upgrading to 202 heads is a very common way to gain horsepower, but usually requires upgrading the intake (better intake manifold and a better carb) and installing headers, to make the most of it. even installing a new highperformance camshaft
yes, iron block w/ aluminum heads.... ls1 has aluminum block and aluminum heads
It's all about the combination, so it's impossible to answer the question. However, it's reasonable to say that the overbore should produce at least 2 or 3 horsepower, the headers could add 10 horsepower, the intake, 5-10 horsepower, and the heads could add anywhere from 10-100 horsepower.
without swaping heads or getting head work done your looking at approximatly 400 hp depending on the cam and intake and carb match.
The headers for a 350 and 305 are the same.
