I know this seems silly to most but a fellow employee was looking to build a 306 for his 78 Ranchero. He's looking to build about 300-350 hp with little cash. I thought some junk yard "p" heads and some pistons that would get him about 9.5 or 10-1 with a flat tappet cam that has around .500 lift and some duration in the 230's would get him there. What do you guys think? Remember motor is carbed and money is a BIG factor. Thanks.
