Re: Phoenix Crank (size)

Ive never measured but are they really meteicated?

Those numbers look suspiciously like 3 1/8 and 2 13/16

Re: Phoenix Crank (size)

Just converted the fractional imperial sizes to metric

Re: Phoenix Crank (size)

I'm coming back after few days. I exchanged emails with Phoenix and they can machined crank with my dimensions for a nice price.

For information for my Rosengart :
A : 3" (16,2mm)
B : Diam : 38mm with negative tolerence [ -0,025 ; -0.041 ]
C : Front and Rear bearing 1"25 ( 31.75 mm)


Just an information, I'm really surprised because Rosengart block are boring for rear and front bearing with a diameter 72mm. I think for Austin is 3.125inch (79,375 mm).

Re: Phoenix Crank (size)

Anyone ever thought of stroking a seven engine with Renault rods, Phoenix specially ground with a longer throw to suit and std height or even Honda pistons? There may not be enough clearance on the crankcase to accommodate the greater throw, has anyone ever investigated to find out?

Re: Phoenix Crank (size)

I'd rather have a block you could bore to 60-61 mm.
I think to stroke the crank you would have to reduce the big end journal dia..

Re: Phoenix Crank (size)

I don't know but I find most 1.5in set ups only just fit in the crankcase as it is. I'm not sure that stroking is the way to go, it I'd be happy to be proved wrong. Like Shed I'd like a block that could be bored to more than 58mm. There are pistons that would do it, I looked, years ago, and could get to 1100cc but the blocks wouldn't stand it.
