Dart Sport 360
Wanna Race?
Heres the plan for our build. Feel free to make comments good or bad. Maybe add things that I may have not thought of. Im a couple weeks away from getting serious so nows a good time to cover all the bases.
I have not purchased anything but an only 1978 complete 440 to steal the block from. AC still worked.
First the other info:
Its going in a 1979 Lil Red Express used only for Bracket Racing
Truck weighs around 3850lbs
727 with approx. 5000 ATI stall (flashed to 4500 with the old 440)
9 Strange with spool and 4.56 gears
29.5 x 10.5 slick
Now the plan for the engine keep in mind we wrecked our old short block so we are re using what we can.
Re-using Pro System 1100 Dominator
Re-using Indy 4500 Single Plane
Re-using Indy SR Heads, Fully Ported, 60cc Chambers, Harland Sharp Full Roller Rockers.
78 440 Block
Re-use the steel main caps from the other block.
Block bored 30 over (4.35)
440 Source 512 kit. (4.25 Stroke, 7.10 Rod)
-27 dish piston.
Calculated with my 60 cc chambers Im thinking right around 11.5:1 compression.
Ends up at 505ci
Cam Ive been talking to Comp and he recommends this custom grind 265/274 .650/.630 on a 110 lobe separation. Open to suggestions as I am not a cam expert . Off the shelf he said 23-705-9 which is 252/263 .660/.660 on a 108 lobe separation.
Roller chain with multi keyway.
Im thinking of going with a main stud girdle.
Going to fit the pan with external oil line and a new pump. Not sure which pump to go with, havent researched pumps yet.
We are hoping to go 10.5 in a 3850 lb truck anything better would be gravy, any less a bit disappointing.
Have at it, hold no punch, let me know what you think or what Ive forgotten.
