A little more Horsepower

[vector1]

he didn't say anything about the gearing, shifting, etc. so you have to figure that is on the good side.

hp per dollar spent? have to be cubic inches. you're talking about a weber setup so you must have the wherewithal to do some mechanical work. the heads are probably not too bad along the lines of 200cc jobs. it's getting on to be winter time also so you have some time to do some work.

you could buy a 4.10 stroke shortblock from kc with the appropriate cam and for around $2600-3000 plus shipping have a 418, buy some gaskets and fluids and help of friends and use your heads and peripherals and you'd have all the grunt you need. while you're at it put a lightweight clutch/flywheel in for little to nothing. resale would be good with a kc shortblock also, jmo. later if you want bigger heads etc. you could work on that. you start playing with the little stuff and you'll nickle and dime yourself to death and have spent the money you could have used on a shortblock and clutch/flywheel assembly easily, and still not have as much power.

an aside: this information is worth about as much as you paid for it.
