Quote: Yeah, I do on pretty much any non boosted/nitrous mopar combo unless I'm trying to kill some torque through the middle or they are exhaust restricted. The only street Motors I've ever worked on that seem to run better on wider spreads and Late ICLs are Buicks and many small block fords. Some small tire A body big block cars back in the day actually with a 110-112 split because they wouldn't hook on the shift recovery.
My 421 with ported Edelbrock heads really likes 106 lsa with similar duration flat tappet cams. Out of 10 cams I tested,106 to 108 worked best. The one in it now is 264/268 @.050 106 lsa and made 578 tq and 620 hp. Nice fat tq curve. Keith
