Should I install a Performer Intake and 4 barrel carb on my stock 307?

I wouldn't say you are exactly 1/2 way. You need a balancer puller/installer. Will need a new timing chain and on and on. I do hear what you are saying though TT. I think a lot would depend on his level of ability. Much easier to mess up a cam install than an intake. Then you almost get into the "why do it to a 307 when a 350 will give you such a better return on your effort. Them 307 heads are small too! I think the intake is a .75 and the exhaust is a .5. LOL

What you really need to do is be prepared that these gains will be quite small in the "seat of your pants dyno"!!!!
