The only headers I can recommend are the TTi & Dougs , Hookers are a poor fit at best , & by the time you buy & replace a couple of ign wire sets you will have eaten up the difference in cost of buy a good set .
I Only Use McLeod Clutches , the B&B / Long 3 finger work the best
the Bets intake is the Holley Street Dom Period , botht the intake & clutch can be purchased through Summit
The Bets carb I have found is the Proform , They are avaialble at Mancini racing for less than the cost at Summit , I would use a 850 double pump carb . Mancini also has the Poly Loc engine mounts which will not pull apart & the electronic conversion kit with dist wiring & ECU , buy the higher priced Mopar kit so you get the fully adjustable dist & for a few more $$ you can swap to a Chrome ECU .
the starter is just a regular mini series from the 88 up Dodge V8 or V6 trucks & vans
Brewers has the belhousing brand new for $300 which is generally lower thaan I have seen it used at swap meets damaged
