Thanks . Due to my not understanding how to contact,or advised people that may have what I want. If not to much trouble could you guys pls forward a request for a A13a tall block to a possible result .As this is what I require to develop this concept . I should be able to find crank here.I have shipping agent here ect. I know its a big call to find one but if dont ask wont get.At the end of the day I wish to exhaust the absoulte an A series can give rather than give up.After spending over $5000 on Cyl head development you would all understand.
Thanks for your patience with me. Cheers Tony

Currently using A12 70 mm stroke 78mm bore = 0.100 to water. 500 lift cam.CP Custom pistons 13.5 cr,Have had to relieve block to get exhaust valve in.My theory is at this compression ratio with 7mm longer stroke longer con rod will increase tdc dwell time to get a better bang on the Methanol. The short stroke engines tried here havent had enough torque of the turns ie Fiats, 4k etc. I Currently rev to 7800.We are 0.5 secs of the E13 pace that are pulling 9500 rpm. Your thoughts appreciated.
Cheers Tony

I agree .Issue I have is the racing rules the engine has to less than 1340cc at manufacture.Hence am wanting longer stroke and con rod for Torque advantage on dirt .Seems A13 acute to US.Canada only one year 1974.I am in New Zealand.
