Anybody recognize this lifters? Bought a truck with engine and have no information on the build.. thanks in advance 🙏

 

I spy some Jesel shaft mount rockers, aluminum, sportsman series pehaps.

 

yes those are on Frankenstein page, but for the lifters I wanted to remove heads and inspect the rest, but might try the engine first and then do a refresh, supposedly it made 860hp

 

Anymore details on that engine?

 

I'll post the cam grind, but don't have much information, I'll be visiting the shop who built it and see how much information they can give me, maybe even the dyno number

 

Here is a link of a recent video they posted, hope it will works

 

 

If you need any info on the heads theres a serial number on the exhaust flange. You can either PM me or contact the shop directly and we can get you details on how we built them.

 

Thanks for the info JR..

I got some more info and engine dyno numbers, this was without a vacuum pump and on VP 114+ racefuel.
Cam = [Intake 680 lift duration at .50 264 exhaust 680 lift duration at .50 274 center 114 lash 28 hot intake and exhaust] what builder sent me ☝️

The engine on the dyno its a SBC, i just took that picture the day I visited the shop.

 

Can not tell from photo what carb and intake and what compression ratio you think?

 

that's just a picture I took the day I visited the shop, but here is a picture of the 441ci. the compression its 14.1:1 intake is a CID 4.5
