Thread: Getting more power out of a 307

Tweet

I forgot about the timing set, thanks, we'll add that to the plans. We're actually excited to get this thing put together...who would ever think I would get excited over a 307!? I guess thats just the hotrodder in me.

Glenn, great plans, and that engine is sweet. You will LOVE the front end upgrade...I used the TCI setup and the 4-link out back...it makes it handle like a go-cart! Good luck finishing it up, hopefully sooner than later.

Glenn's recommendation of the K1102 cam kit is smack dab on the money. Exactly what this motor needs. Timing events are the same as a Crane H-260-2, while lift is just a few thousandths less than the Crane grind.

Crane's description of this cam.......
"Excellent low-end torque and horsepower, smooth idle, daily useage, off-road, towing, economy. Also mild turbocharged, marine applications. Primarily used in 305 and 350 cubic inch near-stock engines for mild performance applications in heavy boats. OK for through-prop exhaust. 2200-2600 cruise rpm's, 1200 to 5000 rpm power range. 8.0:1 to 9.5:1 static compression ratio advised. (50 state legal, pre-computer, C.A.R.B. EOD-225-18)"

Intake opens -5, Intake closes 45, Exhaust opens 29, Exhaust closes -9

Can be used with stock springs on L31 Vortec heads (12558062, 10239906 castings)
