1966 GMC P1000 (C10) Build

[Bdsankey]

I ran 14 to 15 psi on pump 93 for 65k miles just had to be selective with the fuel station. 10.7.1 should be snappy.

Hell yeah!

I'm hoping it makes some damn good power but I am extremely out of place with gas stuff.

Well called BTR and confirmed with them what I should do. They think a flat top (-3.2CC for reliefs) with rods (I'm going K1 HD), their "Red Hot" cam, AFR enforcer heads etc should run VERY well on pump and e85. This would net ~10.7:1 compression which they indicated would be fine at 15-18psi (don't know if that's pump or e85 but I have zero issue swapping pulleys).


The big thing is getting parts ordered so I can get the engine to the machine shop. I don't know when I need to use an o-ring or fire-ring but they indicated a good gasket like a Cometic MLX would be perfectly fine when paired with a decent head fastener.

I Blew past 20lbs on factory GM LS9 gaskets and regular ARP head studs a few times. As long as you don't exceed that, you shouldn't need to O ring it. The tune is whats critical here.

Good to know! I did order the below parts yesterday. K1 is having a 25% off sale and TSP has the rods price matched already. I went with the "HD" rod as it was ~$30 more for the set. I will be using ARP hardware everywhere and H bearings. The Wegner drive kit (for the 3L Whipple) uses an ATI damper so that's covered already when I order that kit.

I decided to go 0.030" overbore to ensure the cyl walls cleaned up and also to ensure I got a fresh hone surface for ring seat.

K1 stuff is good, I’m running their crank and rods in my 408. Did you go overdrive on the balancer?

I don't have the balancer yet, I will when I order the Wenger drive kit. They run a 5th gen camaro offset with 10 rib for the blower drive and a standard 6 rib for accessories.

As far as I understand these are internal balance engines and don't need to be balanced with flexplate/damper so I have not ordered them yet. If both are required I will call Wegner and order the damper they use.
