Dum, I'm not downing your project, but PLEASE get it mapped!! It'll run all kinds of different, you'll be supplying massively different air at different rpms, not to mention it'll be laminar & turbulent at completely different points compared to the stock plenum, so just bunging an uprated FPR on it will cause it to run rich as feck and you'll get incomplete mixing prior to combustion...
Also, unless you're trumpetizing the end of the bodies, you're gonna be ending up with pretty short tracts, which will improve top-end power and throttle response, but sacrifice a lot of torque at mid-range. Which means more than ever the above applies, as you've shifted how much fuel it'll be able to burn at any given rpm and throttle position...
I'm not hating on you, I'd love to do this kinda thing, but imo cams are the 1st port of call, then bodies, as halving the fuel economy of the engine for a comparatively mild gain on a stock engine doesn't float my boat!
Either way, crack on, but please do it properly with the mapping....
