New Design for the Rover V8 Head

[constablergt]

While I have been out in the states I stumbled across a company in Phoenix (TA Performance) that are producing their own custom heads for the Rover V8. He had based the head from a small Buick v6 similar to the 215 Buick that Rover based the V8 we know today. I asked why and it turns out that a guy in Australia is interested in selling them on over there with a new manifold as well.


My Question is: He is sure that the head will get around 300 cubic inches of airflow from this new design.

Q1 What is current air flow on a rover head as I have no idea.


Q2 What performance increases will be possible.

Q3 The new design has valves that will sit flush to the pistons, what will be the difference from the old design airflow/power.

These are some pictures of the work in progress

[quote=mr-scott]These TA heads look to be based on the 231 3.8 litre Buick V6 heads - note the tall slim inlet ports. Way back in 1979 Buick made a major improvement in design to the previous heads which were similar to the Rover V8/ Buick 215 & better 300 heads, I'm sure the V6 heads were like 300 heads with 2 cylinders less (3.8 litre V6 = same cylinder size as 307 ci V8) anyway in '79 buick increased the flow over the previous V6 heads by 47% intake ports and 83% exhaust (high inlet and exhaust port, better short turn radius) as well as making small changes to the combustion chamber shape, they continued improving these heads further with the 'turbo heads' a subject in its self! These heads should be ideal for large capacity Rover V8s, with a minimum improvement over std. heads as stated above - pity Rover/Landrover engine development engineers didn't look at these when improving the Rover V8, talk about an opportunity handed on a plate that they missed!



Found this picture as well, i will be keeping in contact with owner of TA and i will keep you all posted thanks of progress, Cheers
