These model of Dippy's came with smallblocks. That being said a nice roller cam 318 is a fun cheapo build! Cam and little head work, air gap and a cheap Holley 650 DP, throw some headers on and some sneaky 235/60 drag radials any go eat punks in there 5.0's and some import dweebs for desert. Gotta throw some 4.10's in for good stoplight to stoplight butt whippin' and gut all the emissions crap. Heater and AC etc. atleast that's what I'd do
