Engine identification and valuation help???

[JPlonghood]

I know these number stampings are not factory, obviously. Look familiar to anyone or any shop that would have numbered their work in such fashion???

Before being installed into a tricked out 914-6, this used to be a MFI injected 3.5L race engine. It's now running old school IDA48 webers, 3.0 RSR heads, 3.2 cross drilled and chromed (not just polished) crank, Carrillo rods, Mahle 3.6 (?) RSR P&C's (see old photo comparing pistons installed to some other, smaller displacement, piston), custom grind cams with specs close to GE80, 906 style oil filter console, light weight clutch and flywheel package. Twin plug and the heads have been shimmed to lower comp and allow use of regular pump gas.

Here is a link to a video of the somewhat infamous (in this area, anyway) 914 street racing: http://www.youtube.com/watch?v=mgtD_XZbQCQ

Have an invoice/photos showing a tear down and partial rebuild (not run since, other than test miles) done in '08 by Sid Collins at Troysport totaling almost $9K. Motor has been sitting on a pallet since being pulled and a 3.8 993 engine stuffed into the 914.

Debating on if I install this or another, smaller displacement motor (3.0), into my '75 3.0 RS look.

This could be old news to you , but figured i'd post it just for GP . I found this link here on the forum already , in a roundabout way :

Well , I see that link does not work .

You can access the originally posted one on this thread / page 5 / post #43 :

"Silumin..(Rob,Brian,Mark&anyone else)"


I cannot tell for sure if it is the same case with almost the same number (or the same if there was a mistype on Pbase). Seems too close to not be the same. Although yours seems to be pressure cast ?
