well, they aren't exactly new, maybe 40 years old but they are the 300 horse double hump chevy heads, i put a wanted ad on craigslist and got an email today saying "I got a pair for you for $100, pulled off last summer, complete, can bolt on" so yes, i'm very excited about this, everywhere i looked $200 was the cheapest i could find, all thats left is the 700r4, maybe i'll get a deal on that too....once it gets warm enough i'll go ahead and toss that 272/282 cam in and slap the heads on and see what difference it makes, hopefully i'll be satisfied 😀
