    If it's in the budget... BUT the pistons won't have valve reliefs so other than Trick Flow, anything really good will have piston to valve clearance issues...

    If you could locate a stock HO 5.0 roller cam(Stang guys used to just about give them away), that will bump Hp by at least 35... The '86 HO 5.0 'Stang used the E6 heads(one year only) and HO cam, was rated 200Hp vs the '87-'92 225Hp that used E7 truck heads... Were other minor differences in EFI components from '86 to '87 that bumped Hp... Assuming headers and efficent exhaust system, the truck/'87-up HO heads are probably worth 20Hp over the E6...

    Another possibility would be run this Lunati flat tappet cam that's similar to the HO roller(yeah I'm ducking)...:hide: That would allow use of a stock '70s cast iron gear dist...

    Nope they are flat top with a small dish, reliefs aren't needed with the E6 heads... With a small cam E7 can be used, at least a couple of the T-Bird guys tried them had no issues...

    Cam mfgr is mostly preference, all sell similar grinds...

    I'm almost 100% that they're valve reliefs because they're 2 on each side of the cylinder

    Huh, two??

    OHV engines have only one cam... OHC engines have one per head, DOHC engines have two per head...

    A lot of the newer ricer stuff is pretty quick... As long as it isn't something with variable cam timing, turbo, supercharged or a shot of Nawssss, you should be able to keep up... Probably even pass once you get rollin'...

    AFAIK all XXX or YYY blocks are roller, doesn't mean they are built with same heads, cam etc...

    1985 was 1st year for roller cam, was used only in carbed, 5-speed Stangs, nothing else... By mid year most all blocks were roller cam capable but generally hold downs for cam spider were not machined...

    the 92 f150 8.8 will be too wide, have a 5 on 5.5 lug pattern and not match up to the maverick suspension. it would need to narrowed and custom fit to the car and requrie new axles and different drums.
    yes it can be made to fit but is not a cost effective choice.
