It‘s in my ‘73 chevy Cheyenne.I just want to know if there are cold air intake systems that can be installed on this type of engine.
If you wanted to do it on the cheap, compare the core support of your truck, to the '81+ trucks. They have a larger capacity (better flow) air cleaner on many of them (it's about 8 tall, other was about 5) and the ducting to the core support is pretty decent as these things go. Over 3 in diameter, so it easily supports the small block. Will bolt on in place of the '73's. Note: if you get the air cleaner, rip the inner carbon filter element out. It's glued to the intake, but WILL come out. It was an emissions thing. Look specifically for the 305 trucks, GM was doing some wacky stuff in the early 80's, trying to replace all 350's with 305's, so the early 80's truck 305's were getting 800CFM carburetors, and big air cleaners, which apparently helped torque. (Yes, I've owned a few of these trucks, and all 305 ones had 800CFM Quadrajets and the big air cleaner stock) Be advised, cold air increases are averaged at about 1HP for every 10* cooler the inlet air is, the temp difference would have to be 100* for 10HP, which is often considered the break even point for felt increases in power. However, knowing the ridiculous air cleaners the 70's GM vehicles were saddled with, 1 inlet on the air cleaner, the air cleaner alone would be a massive improvement. It will certainly sound better. :)
