8BA or 8RT
I have a '48 F1 and it should have an 8RT engine. The heads are marked 8BA and I don't know if the RT engines were marked as such or not.The dipstick is marked RT. Does anyone know if RT engines were marked 8RT on the heads or not? The truck was restored in the mid-eighties and parked in '98 till I got it a month ago. Having a lot of fun with it!-Bill

Re: 8BA or 8RT
I THINK the heads will have "8BA" on them. I KNOW the intake manifold has "8RT" cast on it. The last block I bought had EAB heads but the manifold had 8RT cast on it and the pan had the large clean out so I'm pretty sure it really was a truck engine. Hope this helps. Good luck.

Re: 8BA or 8RT
Mine also says 8BA on the heads but 8RT on pretty much everything else.

Re: 8BA or 8RT
All of the 8BA intake manifolds also say 8RT, passenger car and truck. I have seen some trucks with 8BA heads and some with 8RT heads. don't know why? someone will say more.

Re: 8BA or 8RT
I have a truck with the 8RT heads. But I have often wondered if some of the trucks came with 8BA heads cuz I've seen so many of them. Hard to tell unless someone has a book because so many of the engines were swapped around...slim

Re: 8BA or 8RT
truck should have 8rt on the heads, most of the 8RT heads were replaced as the years went by with the 8BA heads because the 8RT heads were lower compression, every body wanted higher compression heads

I know the correct carbs had the 7RT on the fuel bowls for the F1-F6 trucks and had the rod choke linkage. The 51-52 carbs had 7RT on the bowl but were called the 8RT if equipped with the hand throttle; both hand throttle and choke lever were cable operated.
