...with stock rods and crank, which block has the most torque???? 2.2?, 2.5 tall block?, 2.5 common block???..... just curious any info would be appreciated, thanks in advance!!!
and the 2.5 T1 high-torque where they gave you full boost ASAP was 210ft-lbs. Course I think the VNT was up there in torque too????
280ftlbs, impressive at the wheels, garrett t3 and intercooled? excites me to try a 14psi 2.5TII pull on the dyno next weekend!:brows:and the 2.5 T1 high-torque where they gave you full boost ASAP was 210ft-lbs. Course I think the VNT was up there in torque too????
My 2.5 dyno'd 200hp, 280ft-lbs at 12psi. It was "mostly" stock. I'm hoping for 300hp at 12psi on my new 2.5
The tall deck block used a longer rod. About .236 longer. The TD block is an excellent choice for a engine build, but needs a stronger rod for a high horse turbo motor. This would mean either $550 custom alloy rods or crazy expensive custom made 4340 forged rods. Around $1200 last time I looked into it. For a NA or low horse turbo motor, adding good rod bolts to the TD rods would help durability.I'd spring for HD rods to get the better rod ratio in a built tall block. I think it would be a better motor than a CB if it's strong enough. Put a 16 valve head on it and it would really be nice!
So better to gain stroke from the crank, rather than the rod?
You don't gain stroke with a longer rod. Crank determines stroke. Displacement remains the same but rod ratio changes. Rod ratio is rods length to stroke ratio. The 2.5 CB has a terrible rod ratio of 1.45:1. This is due to the huge stroke of the 2.5 crankshaft. A TD 2.5 has same displacement but because of the longer rods, the rod ratio changes to 1.51:1. FYI-The 2.2 comes out to 1.64:1.So better to gain stroke from the crank, rather than the rod?
