TBH I've never seen any other Sprinted Toledos, though I never thought mine was the only one! (just the best one, of course
I posted a couple of pics of what was my car (JJB 923K) in the "rally car interiors" thread in the Motorsports section. Dolly-Nut was very disparaging about the (in my eyes) lovely "blood and bones" colours - strawberries and cream if you are of a more squeamish disposition - but clearly he has no taste as he's repainted it purple.
It had a "Detroit Locker" diff - not an LSD really, it locked solid under power but completely free off the power, so you could pootle round corners on the road, then just go sideways on a stage. It was a bit of an animal! When I put it on the rollers (Clifford Cox, in Reading) it peaked at about 125 at the wheels which I was happy with - standard head, just polished a bit; mild road cam and HS8s on a flowed manifold, TT downpipe and system on a standard exhaust manifold, modified advance curve on the distributor. It was quite well-mannered though, no huge flat spots. 4 mpg.
I'd start shopping for interesting bits for MOY, but I've just had the gypsy's warning that the house (where my ex and daughters live) needs a new boiler, so my budget for toys has just been hijacked.
Straight 6 into the Toledo/Dolomite engine bay must be a struggle. Surely not enough room for a radiator inside the 'normal' front? I'd like to know where the engine mounts are on the block, compared with the 4-cyl blocks - can the 6-cyl block use the original engine mounts on the OHV subframe, or does it have to be shunted back to fit in? Weight distribution might make you want to shift it back anyway, though - the Toledo is inherently nose-heavy at the best of times and putting that big iron block and head in would make the front suspension groan!
