Normally aspirated race hemi
Posted: Wed Jun 15, 2011 7:11 am
A Top Fuel team here in Sydney (Australia) have offered to build a Keith Black for my Altered. While the team run BAE / Force gear in their racecars, they have access to a large stockpile of KB parts (1980s vintage).
The biggest hurdle we have is that I want to go normally aspirated and the guys on the team (naturally) only have experience with blown packages. The guys have several original KB blocks available, as well as a couple of brand new cranks. They also have quite a few heads with 160 to 170 chambers (heads are twin plug, but we will be blanking one set of holes off). I have a set of Arias part # 42535HH pistons that should go most of the way to giving me a 12.5:1 comp ratio.
The car will be running a powerglide transmission; not sure yet what stall the convertor will be.
To start with I am only looking for around 500 HP, as my daughters (Junior Dragster graduates) will be 'learning the ropes' in the car. Does anyone have any information on components we should be using to get a good basic combo together, for example head chamber size, valve sizes, camshaft type & specification, manifold type, induction, ignition, etc etc.
Any information gratefully received.
Thanks
