Hey all, long time listener, first time caller... I'm doing a low budget Big block turbo build in a jeep wrangler. Its a basically stock 440 out of a motor home, steel crank, std bore, i re-ringed it and new bearings and i have a new timing set but two cams too choose from. I was wondering which will work better with my goals. Dont really care how much power, but i want to be able to boil off 40" tires...should be fun!! Ones a comp, .470" and 224* @.050 and 110 lobe seperation. the other is a old crane grind, .467 on I , .494 on E , duartion is 222/234 @ .050 on a 114 separation. Im leaning on the crane but since the comp is a single pattern, Ive heard it may work better. any input is greatly appriciated!! Thanks!:)
 
I do believe the Crane will work better in this application with the 114.
An actual check of timing events would be great. They should be available on line.
 
ON the COMP: @ .006 Exhaust close 21 ATDC opens 69 BBDC
Intake opens 29 BTDC 61 Closes 61 ABDC Intake centerline is 106

On the crane: @ .050 Exhaust 56 ATDC (opens) 2 BTDC (closes)
Intake 2 ATDC (opens) 40 ABDC (closes)


Pulled right from the website, why theres no standard of where they measure the events, Im still cornfused... Thanks for the reply Rumble!
 
Try plugging the event numbers into a simple desk top dyno sim and add in the amount of boost your intend on using. Everything should be apparent.
