Can you explain what Stage1/2/3 heads actually mean ?

Absolutely fk all with out flow numbers

Fair point, but in general:

1 = In/Ex port tidy up....some think this is polishing but its more about shape....the polish comes as a result of the kit used to get the shape and repeat the size/shape consistantly. Sized and matched chambers. Would normally include bullet guides. Skim for desired CR.

2 = Stg 1 plus bigger inlet valves.

3 = Stg 2 plus bigger exhaust valves. (if there is room, or best size combo for the space)

Options on top of these are different/double springs, compound angled valve seats and matched ports to manifolds.

And Robs stage 4?

I would be interested to know why a TVR 5l engine makes 270 and my V8D engine makes 343hp .. I know it has a after market ECU but 73hp difference is a lot .

I daresay I would be impressed ,but point being I should be for what it costs.

Be a poor show if there wasn't such an improvement.

Please note everyone, a prominent Griff owner has just admitted (in public) that he'd be impressed by a Chimaera

Wasn't he implying to be impressed by only the engine ?

I don't think so, and anyway, you should never let the truth get in the way of a good story!

Absolutely ONLY the engine ....

Though on the plus side from sitting inside the car enjoying the engine I wouldn't be aware I was sitting in a chim. so it wouldn't be that bad
