1992 Griffith 4.5 big valve

[SRT Hellcat]

I have the opportunity to buy a one owner 1992 4.5 big valve Griffith.
I am being told that it is 1 of 9 cars built.
Does anyone have any info on the 4.5 BV engine, are they pretty reliable.
I am aware to make sure that the fans are working with regards to overheating.
What sort of oil pressure readings should I expect ?
Also to check that the chassis outriggers are in good condition but I am being told that this can be difficult to check effectively.
Any thoughts and advice would be very much appreciated

Very unusual car, the engine was built by NCK who are now Powers, info seems to suggest it had a crossbolted steel crank and rods, cosworth pistons and big valve heads.
A very nice engine and described as probably the sweetest of the lot.
Chassis condition can be tricky to inspect, if no history of outriggers then no doubt it may need some but depends how its been treated.
Really needs a thorough inspection on a ramp.
Oil pressure difficult to guess at but I would expect to see around 35 to 40 psi ish on a hot engine, how accurate the senders are is another thing.
Not many know they exist.
