Naw, I'm going 427 BIG BLOCK !!!!!!! I'd like too find a dual 4bbl intake manifold (Not Tunnel Ram) but a single 4bbl will work. I think a 427 BBC will be a lot of fun in a 5th gen (78 to 87) El Camino. In all honesty, I'm building more for the WOW factor then anything else. I'm going for a fun street rod. I think it would be very fun too go on the HOT ROD Power Tour. 427 BBC backed by a 700r4 and a posi rear end with 3.73 gears. Hotchkis Preformance Suspension, (I'm thinking thier TVS + tubeular A-arms) Working A/C and heat is a must. I know it will not be the best set up for MPG's, but that's not a big issue. It also won't be the fastest thing on 4 wheels, but I'm not going for a race car. I guess what I'm really after is just a street rod, a weekend cruser.
