FWIW - I did an AI comparison of all the pictures and it came up 100% certain it was Dove :) and all the reasons it told me so.  It even sent me for more pictures to prove it.

So the game plan is this.  Many of the parts are in the recently built engine, so you'll see some odd choices compared to most of my builds.

Dove aluminum block - I just pressure tested, all good and was running and likely doing well as drained oil and indications of a good burn pattern across all 8.  Going to tighten up the main registers a little, align hone due to crooked mains and full CnC prep. 

Ford 3.98 crank - already internally balanced, will mag, verify balance and run with a polish if all good.   

Eagle 6.49 H-beams - found two caps swapped by prior builder, game plan is to check bore sizes and swap caps back, resize as needed.

Ross flat tops - 2618 pistons with 1/16, 3/16 rings.  This one may not stick, need to see piston to wall clearance, if we can get there with a torque plate, we will reuse with a set of Mahle rings, if clearance is excessive will go Racetec with 1mm/2mm pack.  Currently flat top.  Will be shooting for around 10.5:1 compression max, if specs good will have to CnC a little repeatable dish, but we'll see after I pour the heads

Custom flat tappet and tool steel lifters - No oil to lifters, so going a little conservative with a Nitrided iron core and tool steel lifters, probably going to end up with a 6000 RPM peak for a street car with a snotty LSA, more to do before I can pick a design

Dove SK heads - will put on the flow bench this weekend. They look hefty on the intake side, not too sexy on the exhaust.  Once I get numbers we'll see if they need rubbing or just a modern valve job and good seals.  I expect these to be pretty stout

Intake - Customer initially wanted a TW and dual look-a-like carbs, watching budget a bit, but will pin down before cam choice.

Should be a snarly 452-ish inch all aluminum Dove based engine in a TKX/4.11 T-bolt tribute

I like it , or find an old Dove TW and do a all Dove build! But for the money the TF is was above average.

Dual 600s from Drew planned for this one, all for a matching Dove but not sure it'd touch what I can get TFS for.

Shoot me a PM if interested in selling it bare, I'll talk it over with the customer.  Thanks!
