Those both look awesome. I am interested in the differences between the two fuel and ignition setups. Both appear to be MFI with timing control. How different do they perform, all else being equal? Is one setup easier or cheaper to configure?
The one on left is a 403 with MPFI. The one on right is a stroker small block coil on plug MPFI. The stroker is flex fuel E85
Both use AEM ECU’s. Cost wise the MPFI fuel injection and the electronics is 4-5k alone. Be patient as shortages and things took a while to get everything
The specs and such are posted in the high performance forum. .
Mark can tell you more about them and the costs. I supplied the heads for the 403 and paid for the electronics and such early on.

Thanks for the extra information! I recall seeing some of this in the High Performance forum, but I will be sure to go back and review it again to find out more.
Congratulations! I think that both of these will be fantastic.
