Already zf-5 swapped

I was under the same impression just going off the word of the seller who is likely unfamililar

Good luck, but I would take a good look at this mine field before I take the first step.
I'm aware I'll likely end up overspending,really just want advice for parts with everyones understanding it is a low budget build. And of course all of that will be gone through, how could I swap a cam in and not reseal the engine...

I went from driving 351W F150s with E4ODs and 3.55 gears in them to driving a 351W F250 with the ZF5 and 4.10 gears. You might find yourself content with swapping out gearing until you decide that you want to put several thousand dollars into a new engine build.

I too went from a 3.55 to a 4.10. I tow a lot and I dislike the slightly higher RPM, but my truck does maintain a higher speed up passes. I would love to get a 6R80.

Do yourself a favor and look at all the threads about the seized coolant pump/front cover bolts. There are plenty out there. Highly unlikely that you will be the only one without an issue AND on a budget. Usually when I am on a budget, everything fails and every step forward includes two steps back. On benefit is that the engine would be out.

H.O. cam great for budget, we run one in my pal's 351W swapped '89. Maybe can regrind it for bit more ***?

Also has basic bolt on junk like my 302. Underdrive pulley set, 1.7:1 Cranes, long tubes, 2500 stall, Efans, and hmmm about it!

Scoots good even with the pegleg 3.55:1

I’m sure I have seen it in one of the many threads but how does that compare to the stock 351 roller cam?

H.O. are .444 lift, around 115.5LSA. I believe 206/206 duration

351W roller is around .400 lift, about 197/204? Unsure LSA. WAY better than the flat tappet crap cams. I think 302 roller used the same, probably wrong, yet both received a far better unit when went roller.

Apparently 87/88 speed density H.O. cams were a hair spicier. '88 in my 302 as had available on the shelf.

Melling lists specs for stock replacements if you want to look them up

Good enough guess for government work!

Note, these are all mass production. So some will rock a Cam Doctor different. Tooling wears, just like your hunting rifle...always neck resize.

Regardless, it is a good cheapo camshaft. NOT great, NOT the best. Sure beats the massive cash they run now, I am floored at their costs

I have read and saw tests on Engine Masters that split duration cams are better so I’d use the F4TE cam with 1.72 roller rockers.

Roller block with non roller Cam?

So I picked up the engine a couple days ago, casting number was f4te-6615-aa. But popped the lower plenum off and there are no keepers in the valley, could I have a roller block with a flat tappet cam?

Are the lifters roller? F4 is a roller motor.

I doubt someone put link lifters, but it’s possible.

Take pictures of the lifter valley, that should tell the tale.

Both of my 1993 Lightnings had F4TE blocks with flat tappet cams. Very possible for regular production 1993 trucks to have the same, IMHO.
