Is there any way of getting 140 kW to 150 kW out off a 250 pre cross flow without geting a 2v head? I was thinking.....
Extractors and exhaust which ive already got
350 Holley
Crow cam
Electronic ignition
Standard 250's in XA's are 116 kW and my engine is pretty fresh (99,0000 miles). I would be happy with another 30 kW. Is this possible?

I'd try and upgrade to a 4bbl carby - like a 465 holley.
What compression are you running?
What fuel are you running? LRP, ULP or PULP??
