Thanks Rodney, will do as you suggest. Can't wait to get the rear back from Mike Dyer. He is modifying your trailing arms to work with my 1480 series axles!

Yes, and ask me how I know about it.
OP: Are those lifters rebuildable or do you have to simply replace them after a few thousand miles?
427HOTROD knows how to keep those solid rollers valve trains runnin good...

All Morel solid roller lifters are rebuildable for about half of new.

Chris, a question I have wondered is when the lifters wear and are rebuilt, how much does lifter bore increase typically with wear? I know how important lifter bore sizing is on these deals so wondering if anything can be done short of bushing the lifter bores.

Morel's surface finish is based on the same finish they developed with a top NASCAR team. Depending on the lifter bores, camshaft lobe profile, pushrod flex the wear can be minimal over 10's of thousands of miles.

Finally got the cam swapped and on the Dyno. Posted the old and new sheets below. Engine is an internal balance 502, 10 to 1 compression, AFR 315 heads, ported Holley Strip Dominator, ProSystems 1000 hp 4150 carb. Only thing different is cam. Old cam was a solid flat tappet. Single pattern 258 @ .050. .609 net lift on a 108 LSA.
New cam is solid roller 263 @ .050 intake, .687 net lift. 269 @ .050 exhaust .668 net lift on a 110 LSA. I am using the Morel pressure fed bushing lifter per recommendation from Chris Straub. As he said it would be, lifter sizing was perfect.
Mike Jones told me it would make 50 more horsepower at 500 more rpm. I guess these cam guys like Jones and Straub know their stuff lol. Sounded awesome on the Dyno. Both of these were done on the same Dyno, 13 years apart although the engine has only done 2500 miles in that time.

Excuse me Mr. Townsend, can you not read? It is 653 horsepower. That extra horsepower should be just enough to let me pull on your turbo civic. I could only find a steel tow hook. Unnecessary weight. ����
