Alex Arrow Don,t give up to easily,I think a mildly turbo-charged stove bolt 235/261 might be a good shot. With hood clearance in a truck you could turn your manifold upside down then you have room. ! have a Buick grand national turbo on the drawing board and dragsix is onboard to try it. Had one turboed but that engine was too far gone. Another thing the turbo should see the fire belch out when the valve opens !!
