611hp naturally aspirated stroker

Looking at this on eBay : http://www.ebay.co.uk/itm/Chevrolet-V8-Ls1-ls2-Eng...

Looks like a well built NA LS motor can make good numbers.

Here's hoping my stroker build will do well too (though probably a bit less power, as it needs to pass an MOT on cats)

Nope there arent any wheels on that one.

If they are stock LS1 or LS2 heads, thats exceptional?

(oops, didnt see that carb)

Heads are ported and have been treated to lots of goodies. Richard would approve

LS1 or LS2. If LS1 then very exceptional result.

Id want to know what heads were on it and the cam.
No mention of either of those.

Knowing this would tell you how driveable it will be on the road.
Id want good heads and smaller cam rather than the other way around..

Interesting article on heads. Old cathedral aint that bad.

Well my understanding is that the heads with larger intake valves/ports are there specifically for power AND economy.
They allow a much smaller cam to be used and still achieve good numbers with economy. (Because you are using a smaller cam with wider LSA)

Id hope the Ebay motor had aftermarket heads, or at least good ported LS2 ones.
Im sure the cam wont be small though at that power rating. 24x/25x Im guessing.

Nice one. Makes me feel a bit better about staying with them (cathedral) on my stroker. In any case you could have the best flowing heads only to be throttled by a poor intake and tb set up with either type of head.
