And one of two manifolds that shows the difference in inlet port sizes between a Holbay (small) and a standard alpine (bigger)

The guys at fastroadcars.com in the UK have the goose neck intake in stock.

This will buy you a little space in your engine compartment.

Just sharing.

From some of the replies, it seems some do not realise that the pics were apparently posted 3 years ago. Strange thatc thev original poster does not appear on the member list. Giacomo just highjacked the thread to post his totally unrelated request for help. I think he has his answers.

Thanks to Rich for sending me the pics!

Its interesting to see the head mods.. they look like a largely stock 1725 chamber thats been slightly enlarged around the end of the bowl.. kind of a compormise between a larger profile of the stock shape and the vizard mod.. i assume this is to keep compression up. wuld be interesting to compare it to jarrids custom chamber head.

I also note they have welded the cresents on the water passages.
