Thread: Getting more power out of a 307

Tweet

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)
