5.7 HEMI Vs. 408 Stroker

It does help, thank you. But no, the engine is a flat tappet head set up. And while I am not in the mood to throw money around, I also don't want to skimp. So is there a better, easier, albeit pricier alternative to the "retrofit hydraulic roller" you suggested?

Sure!! You can just put a flat tappet back in it. I have used several Hughes engines cams. They make power! so a combination of stock bottom end with an Edelbrock air gap intake Summit Racing $259.95 , hughes stage 1 heads, with the correct springs and retainers installed ready to install $1377.40, HUG HEH2328AL cam $160, lifters $88.00, 1.50 Roller rockers $440.00 and pushrods around $130. I just picked a combination. Subject to your own judgement. Cam should be slightly lopey but not insane.:toothy10:
