Blucille thanks for the link, others, sorry should have given more details in post, the engine is a 70 2.2, blueprinted and built by Bob Farmer in Indianapolis, to 2.5, S cams, 2.7 crank, honed and polished, dyno'd at 225, bob likes cis and that is what it had when I bought the car, I just really like the look and sound of the early mfi cars, have also considered PMO ITBs but like the nostalgic look and that's why I am looking into mfi conversion. Didn't really want to tear the motor down and start over but I know how one thing leads to another, leads to twin plug, etc. this car is only for the street and I plan on keeping the AC, any additional thoughts? thanks, you guys have a great weekend, robb g
