Need ya'lls advice pretty bad
Ok here goes, I'm building that 1969 350 that I originally thought was a 302 for my '88 S10. It's gonna be my everyday driver in the Spring, Summer and Fall and probably alot of the Winter unless we get some snow. I have got the bottom end together, mic'ed everything after cleaning, polishing the crank, honing, thrust play, plasti-gauge the main and rods etc etc and everything checked good. I knocked the cam bearings out before cleaning and really gave the gallies some extra attention, installed new bearings and brass plugs. It's standard bore with 4 valve relief flat tops that were in it and I will be measureing the quench tomorrow if I can make this decision to know what head gasket to go with.
My delima is this: I have a stock pair of "186" DH, a stock pair of "062" Vortecs, can get a pair of Dart Iron Eagle SS 007 heads, that were used foe mock up only, for $350.00 that have 72cc chambers, 1.94int. 1.50exh. that need nothing but my springs and a set of plates, can get a pair of "906" Vortecs that have been surfaced .010 with screw studs, plates, guides have been cut for retainer height and PS seals, spring seats cut larger, cut for 2.02/1.60 and come with new Manley 2.02/1.60 valves for $500.00. I have all the tools to cut the guides, seats and stud bosses, tool to pull the studs and tap for the screw studs if I go with the Vortecs I own. I'm going to have to either buy screw studs and plates for the "186" heads and if I go with my "062" I'm gonna have to buy screw studs and self aligning rockers, it's cheaper than buying the studs, plates and non self aligning rockers.
I'm running the Summit K1103 cam, lifters and have the correct springs. I have been practicing on porting on a pair of "882" heads I have and when I feel comfortable enough I will be doing the porting on the heads I use on this motor. I have a couple of dual plane intakes for the old style heads and have one Professional Products dual plane for Vortecs. I'm running a 3.73 gear with an Eaton limited slip, TH350 with a Hughes Tow Master converter, rated at 2000 stall.
I want this truck to be a real sleeper and completely come alive when I call on it. I want to run 93 octane and probably a 3310-4 although I have several, several different carb choices as I have a stock pile of Holleys. I bought a couple of David Vizards books and have been doing alot of reading. I'm going to run long tube headers and am looking at a pair of Walker mufflers that are suppose to flow very good but also be almost OEM quiet. I'm running 235/70/15 all the way around on 15X8 Rallys. Can ya'll give me some advise on the best route to take on the heads? I'm not really concerned about the cheapest way, I want the way that will make the most power for what I want the truck for. It will not see the drag strip most likely, well, maybe once just to see what it will run lol. I know I have probably left some things out so if you need anymore info on this build I will answer asap. Thank ya'll very much.
