re curve distributor necessary?
hi folks,
As some of you likely know by now I am rebuilding a 2.7 motor with euro RS pistons (8.5:1) and E cams. I have the original dizzie from the cis motor. Do I really need a recurve? Reurve prices from all the usual suspects run around $400. That plus a new cd box and pertronix is getting into crank fire territory... |
Yessir, you should have the CIS distributor recurved if you want maximum throttle response and performance.
IMHO, its not only well worth the money, but it runs decidedly better compared to crank-fire distributorless ignition systems. |
will you be using carbs ?
|
assuming that you're using carbs, why not look for a distributor from a 2.4E motor? Will be cheaper than recurving and you get to keep your CIS dizzy to sell and offset the price.
|
yes using carbs...

Steve,
theoretical question how would you feel about a locked down distributor on a race only motor that never see's below 4K? I'm debating recurving a 2.4T or not, for a 2.1 race motor I'm in the middle of. my gearing allows 5K exits from all corners. (unless I really screw up something) brant |

Brant, If its a single-plug motor, you'll play hell getting the engine started w/34-36 deg advance. Twin-plug engines do better @22-26 degrees but high compression ones can bite back and will break the starter and ring gear. One reason I use MSD's on such engines is that I can use a 20deg start retard feature to get it running without risking the starter and ring gear. |
I always learn something here
thanks! brant |
