Stroker block serial numbers

[304runner]

Got a call from a friend who asked what serial numbers (or part of) to look out for when buying a VS 5ltr block as they are factory cleared for a 355 kit. I couldnt help him, so was wondering if anyone could give me the info to pass on.. This will also confirm if the VS SS block I have got is the real deal too....

Cheers!

This is in the VS range or 215i engine numbers - this one came from a Grange but not sure if the 215i was the stroker motor.

If it is your looking for a VL prefix.

From what I know, VR series 2 onwards blocks are factory clearanced for a 355 stroker. These blocks also don't say the capacity cast in the side i.e. VR series 1 and older will have "5.0" cast on the side.
This is info i've had passed onto me so cannot confirm 100% that its correct?

The only 5.0ltr blocks that the factory clearanced were the VT Aussie V8's.

Incorrect.... The VS V8's were also a factory cleared 355 block and I also think the VR GTS had the same in them too. (not 100% about the VR)

But, the block I have in my garage for my build starts with a "VU"xxxxxxx.... Any Idea whats thats from fellas?

Wrong. All blocks VR onwards. I always thought it was all VR blocks but stand to be corrected if it was series II onwards. I think you are getting confused with the VT (and VSIII) 5 litre roller cam and multi port efi motors.

VU prefix ran from VN - VS so it could be anything. Grinding a block to suit 355 ci is easy so any good block will do.

Yeah Just a little nic with a die grinder and she's sweet I hear....

Its only to stop the bolts from hitting I think.. Bugger all to take off really....

Pretty much as above; I remember when the 348ci 215Kw motors were released (joint venture between Harrop and GMH?) and from then on all factory blocks could run the larger stroke crank.
