I also think that i was racing Daz Chandler helped me alllot...
Well done Rich !! Do you feel the 51.5's are helping over the 48's....assuming the choke / venturi size and jetting has remained as was with the 48's ? Or the stinger as you usually run with the muffler right on 12 zeros's ?
Thanks for sharing,
Shane.
I ran the 11.97 on 48's and muffler..
The 51's have not be jetted the same as the 48's the vents are bigger. They came straight of Daz's 2 litre motor and the A/F was pretty good so i left them as they were..
In reality i only run 42x37.5 valves so the 48's with 40 vents and the smaller header plus muffler should work better.. with larger valves it would go even better...
I will be building another motor with large heads and the 51's on soon so we'll see what numbers we get then..
So to answer your question.. honestly i don't know.. only a dyno would show the results properly.
