Thanks for the info! I wondered about the mass air and throttle body. That intake and stuff were on it when I got it so I just used them. As for the block I was told it was aftermarket and good for much more power than stock. I have all the receipts from the original owner somewhere. Any recomendations on intakes? I didn't build it to go slow so if I need to make some changes then now is the time. I had the heads flowed and if memory serves me correctly they flowed 192cfm on the intake side. They were pretty extensively worked over and the machine shop that flowed them told me I was plenty good for that cam and to feed the stroker. I'm glad I asked now. Ida been pissed if I would have gone to the dyno and found out I needed to make changes like this. I'm near hagerstown. Thanks again for the info!

Thanks for the reply, I had the heads flowed after they were ported to match all the volumes and they all flow 192cfm. I worked at a machine shop that builds outlaw sprint car engines and that was my job, to port the stack injection manifold and cylinder heads that we didn't have Cnc ported. Comes in handy sometimes. New heads weren't in the budget and having access to a super flow flow bench it just kinda made sense to use them. Thanks again!

Thanks for the info! Ill check him out. I only picked mpc because I know George and have a history with him an I trust him. Ill Definatly give dgr a call after I get the hard parts right. Sounds like I have some changes to make here and that's ok. That's why I asked. Thanks again

......., but furthermore is if the car is already together, when Masondixon REOPENS in the early spring is go run it and see what it can do, that way you'll know where the combo needs to be improved, do the heads have 2.02/ 1.60 valves??? and Hagerstown ehh?? I'm in Frederick .... small world 
as for aftermarket block...there was no gt-40, they had b-50 sportsman blocks back in the day , now discontinued that had a little thicker webbing and then there are dart, world products and boss blocks which all cost a pretty penny, any pics of the block or ID that it is an aftermarket??? I pass mpc on the way home every day, I have a s/c vert that Dgr will soon tune once I get the meth kit on it, I'm goona just do the chip tune thing, while I have extensive knowledge on the subject, I just don't have time at this point in my life to play with a tuner for the learning curve it requires.

I went with the Holley Systemax on mine, with 80mm TB, 90mm MA, 42# injectors, AFR 185 comp heads, 223/227 .610 lift cam, 1.875 Kooks headers (with 3" exhaust manifold bolt spacing), and 3" exhaust. Used an SCT chip and made 425 rwhp and 425 rwtq. Cam is relatively mild, and the exhaust, especially the headers, is a little big.

If you are seeing 192 CFM thats about 75-100CFM short of where you need to be to really make power with a 347 type engine no matter what the tune...........
