Hey guys, have a 88 Monte SS,the stock l69 is junk(heads were pulled off and sat for 15 yrs with just a sheet over it) althogh it still turns over with minimal rust in cylinders. Question is can i build a 327(think from a chevelle maybe '69?) and put it in front of the stock 200r4? Will i need a different flex plate since the original is from a one piece rear main seal? Got a set of worked camel humps sitting on the shelf and got me curious about building a streetable 327 for the 88. Thanks for any insight, also if anyone has done it can i get some pointers and pics?
