I'm not angry just a tad disapointed is all.
all this crap under the hood and it really is not any faster than my old .040 over motor.
lets see
.040 109 junk replacement cast pistons(heavy as hell) 200/200 flat tappet lunati cam bob stanley ported heads 1.65 roller rockers and a ported intake. the compression was just a tad over 8.1/1
it has ran a 7.21 @94.5 mph with a 1.65 60ft. shortly after that pass i hurt a head gasket due to the walbro pump giving up. on race gas
so now i have a
.020 109 diamond pistons stroker crank roller cam Ta alum heads with 1.65 rockers ported intake and a girdle. the compression is a full point higher.
it has ran a best of 7.17 @ 96 mph with a 1.60 60ft on pump gas @ 16 psi of boost with 22 degrees of timing.
so thats 5 psi different. so the bigger motor ran almost the same time @ 5 psi less boost.
but the bigger motor has more cubic inches (21 to be exact) and a full point higher in compression and it has a bigger roller cam.
that to me seems like it should be faster with less boost than the old motor.
I hope something changes my mind cause right now i'm regretting spending the money building this motor. All the other motor needed was head gaskets and a oil change
