I'm quite happy wiht the 4503 as a good all rounder cam, even on stock compression it runs quite well, but anything extra you can throw at it is desirable.
I think the stock converter might be pushing it a bit though, the 4503 doesn't really come on song until 2500+RPM and also it's idle is a bit grumpy I reckon you'll have to be pretty heavy on the brake pedal at the lights.
Also if you take 30 thou off the heads you can get away with running 30 thou shims on the rocker pedestal (I think crane does them) which will fix up your geometry rather than buying new pushrods.
I'll probably go something with a 108 or 110 LSA for my next combo though.
I think having the 4502 now you probably won't see much gain in a 4503 on a stock engine to justify it unless your after it for the idle characteristics to be honest. The head skim will wake it up a lot more than the change from a 4502 to 4503 would.
The idle would be nice but I can live without ( and if it surprises = me/and people a bonus ).
Recon If I do ,I'll go the shims = also make more sense , not just cost but the differences = a little compression and Starr = how they perform.
Keep me happy along with I really do want to refresh exterior.
Seen what a great job you have done on yours but while I'd love to give it a go , I'm figuring/ budgeting someone else is painting mine.
It needs other stuff = want new shock springs.
Need =( well it's really me want better brakes ).
And then a little more down the track a nice 355 streeter.
