Stock cam, heavily ported head, stock valves. I may have been running a slant 2bbl Holley at the time. No power steering, not running the dealer installed AC.
70 with the AC on was 16.7.
I did a few Bonzi runs in my day Naples, to Nashville and back in the 198 Duster. 82mph with 3:23's (it came new with those) and the 3 speed manual. 22mpg.
Check with Music City Mopar Club. They might know someone who has slant stuff. My next door neighbor has one in a van that I am going to probably buy. But I think I want the motor etc. Might want to do a cast crank motor for my Duster.
Tony Defeo (Whitepunk on Nitro) he might have something...
800 cfm was the smaller TQ. (maybe a Carter fib on the size) A properly tuned air valve on the secondaries will give all the air the engine demands. Some 360's came with an 850cfm. IIRC the Mopar Q-jets were 725 to 750. Triple boosters on the primaries. I pulled a nice one off a 318 van. It did...
Back in the day my Formula S got 14mpg combined with 3:23's. It was a 511"RB. The trick is 2bbl's get better MPG. Mine had 3 of them! I suggest going that route with yours.
Combined MPG = 7 in the city, 7 on the highway :p
I want to go EFI/turbo eventually. Lighter reciprocating assembly, possibly a lighter block too. The cast crank should handle a turbo. Narrow the rod ends so I don't have to buy K1 rods.
600cfm is kind of large. Whatever happened to the 390 Holley's?
I used to run consistent 10.58's in the 1/8th with 3 on the tree, 198 open 3:23's, M-1 intake 318 BB or a Holley 2bbl off a slant. Stock valves and cam, Hooker headers with a H pipe crossover duals out the back, with Superior...
Cast crank engines have narrower rod journals don't they? I was wanting to pull the rods out of my '72 198 to use that engine for the lighter crank, and if I remember right lighter block.
I am eyeing my neighbor's '80 or '81 van. A friend used to own that van and I knew that van when it was...
Infrared gun told me #4 was pumping @ambient temperature. I had drilled out a jets on a BBD which mad it pig rich on the dyno. I may have wiped the rings on my low mileage 198. It has been sitting since 2009. Driving over the road left me no time to play with it. When I came off the road it was...
