OK, so I haven't posted much about my project. Its a 67 Dodge D100 getting all late model '96 C4 Corvette suspension (dont bash, it was way cheap, or I'd run Viper stuff!!). I plan on running a Viper 6 speed trans, but have yet to decide on an engine combo, but it will be turbocharged. I have a std bore 69 340 block and some Eddy Magnum heads, but I don't want to blow stuff up. So I have been considering a 48 degree, siamese R3/W head combo but I just cant ignore how "cheap" the R5/P7 stuff still is. Any thoughts on how much boost the R5/P7's can handle? I'm most concerned with head gasket sealing, not block strength. Do the R5 blocks have a good sealing surface compared to an 18 bolt R3? Perhaps an XR block would be a better choice? Thoughts or opinions? Ryan?
