Trying to figure out exactly what year 302 motor is in my F100, and a guess at horsepower with current setup. It is mated to a C4. I can take more photos of specific areas to help confirm. Pretty sure parts are from all different years so need to identify piece by piece 2150 carb 1.08 Venturi size 49 jets
Is that casting number E1TE? That would be 1981, maybe into '82. If all stock and the heads are from the same time, pistons and cam etc are all what came with that block, you might be at 130 to 140HP.

Here is a better photo of it. That's the thing.. nothing is stock, he took parts from different years and motors and put it together...
That is a late model roller motor which means '87+ and that would match the E7TE block casting number.
Those are E6SE heads(capital S in the top outside corner)... the absolute worst heads ever produced for the SBF if you want any HP, great for torque with the kidney bean shaped combustion chambers but then it's a 302 so it's all relative.
The combination of those two suggest this was likely an '87-91 Crown Vic/Towncar motor, the cam is unknown... but if it is original this lump was rated at a wopping 150hp and 270tq.
These heads were designed for the '86 Mustang, in that car the motor made 200hp with the HO cam, that shows how small the base cam is but it also shows how bad the heads are, swapping on a set of E7TE or F1ZE GT40 heads(with the HO cam) adds 80-150hp!!!!! The flattop pistons become a limiting factor with bigger cam though.

Damn... Well that’s disappointing about the heads. Guess it’s not worth doing much without swapping those heads? Maybe I should just get it running decent and forget about performance/HP. Is the 87 roller cam block desirable atleast? With all this said, what do you think I should shoot for as far as baseline timing goes on this setup and is the 2150 1.08 49 jet size appropriate. I just rebuilt the carb thanks to lots of help from redroad and I’m about to fire it up for the first time in 4 years. Already primed the motor via the oil pump all new fluids. Plugs gapped to .035
Yes run it and see how it does, if the PO swapped in an aftermarket cam then it will become obvious real quick there is a mismatch, the motor will be soft at low rpms, start to build some power and then run out of steam again where it should really start to scream. With the stock cam it will be quite torquy right off idle but then almost immediately seem like it's sucking through a straw. Head swaps are easy enough to do down the road, those mentioned above are direct bolt-ons nothing else besides new gaskets required. Thet roller motor is definitely more desirable than the flat tappet version, there are loads of cams that it can use and while it doesn't have the strength of a 5.8 block it can easily be a reliable 350hp motor with bolt on parts.

After reading more online I’m confused... do I use the old style 302 firing order or the 5.0 firing order
Actually it could be either and the one that works will hint at what cam is in the motor. The early EFI motors still used old 302 firing order... that includes the CrownVic/Towncar version, but the Mustang, '94+ truck, and most aftermarket roller cams use the 351/HO firing order.
You got a 50/50 chance of getting it right but I'd be tempted to start with the 302 firing order. The good news is you don't have to worry about cam breakin so it won't hurt anything if you have to make several attempts to get it running smoothly.
