How much horsepower should I expect?

Subsitute a Holley 950 for the Eddy 750 and your horsepower will increase....

I agree..the shorty headers will cost ya...


yea but he's in England with $7 a gallon gas or close to it, I would keep the eddy--it idle a bit better also and hold its tune and you can adjust the a/f without dumping that expensive fuel...changing metering rods and springs beats holley jets and power valves

if your drag racing then its another story.
