I'm thinking about a trade with someone. I have some pretty good dragracing heads. I'm not sure the specs on them for now but when I get home I'll check that out. They were on this truck that was able to pull a wheelstand and break his 4 speed muncie so they are a good set of heads. I'm probably not going to use them for my car cuz I still have a stock 305 and it would take to much $ to build up to something that would handle those heads. So what I'm thinking is a trade. I know someone with a set of vortech heads and a TPI system which has the computer, harness, injectors and all that stuff. It came off his car and I know him pretty well. Ran just fine when he had it. No problems at all. Well he wants to sell that setup. Think its worth the trade? Well You dont have much to go on here but I will get the spec ASAP for ya.
