you actually answered a few questions i have had for the longest time!

im trying to start with a holley 390 / offy intake... so far i have a 390 that needs cleaning / rebuilding. i dont know what it came off of, just gonna start with .50 jets and go from there.

it gets kinna cold around where i am so intake heat is pretty much a given, but i want to run long tube headers. im not sure, i think the offy intake is ready to go as far as plumbing in water from the engine to heat it. that saves on having to buy a heat plate, but if not, hafta get a plate to heat that carb. its basically as the name implies, a plate that you mount either under the carb or under the intake manifold, and plumb into the engines cooling system to provide heat. although the offy will bolt on to the stock exhaust manifold, so no plumbing needed, if you go that route.

those fuel injection systems are lookin like a pretty sweet setup tho... i wonder how well itll run in a turbo setup.

also tall tires might be a possibility, you didnt mention what transmission you were going to put behind this beast. both of mine still have the 4 speeds in em. doin freeway speeds at 3-3500 kinda sucks, and ill take every couple hundred rpm i can get.

since nobody said it yet, leo santuccis book, the chevrolet inline six power manual 2nd edition. its a good read with alot of helpful info.

inliners.org has a great board on it and some pretty helpful people. look up tom lowe on there, hes a great guy with lots of dyno info on these engines equipped with these parts, and theres many others wih a plethora of other info, you need only ask!
