"Hey guys, I'm trying to make some budget power from the junkyard to make my $500 87 B150 van run a bit better. It's got the factory 2 barrel carb and single exhaust, so it'll be hard to make less power."
Stick a 340 cam in it and see
No matter how many times its said the stock 340 cam in a 318 sucks is BS. I have personally done it 3 times advancing it by 4 degrees and it works very good. Power
increased from bottom to top. Real cheap out is find a good used 340 cam w mating
lifters (old quality stuff) thin head gaskets, may get it going for 100 buck? I have also used high rate roller cams in 318 yeah they work a bit better. Its very easy to spend
other peoples money, you got a JY engine in a van... cheap out and have some fun.
