The best stroker 408-416-426-435 combination in stock 68 340 block
Didn’t you just say... Hypocrite LMAO
And increasing the stroke doesn’t help?
ROTLM-MF-AO!!!!!!!!
Its seems like 75 % we get each other and the rest we're 180 in opinion.
I not trying to talk the OP out of stroking his engine. Just trying to explain stroking is not for more power just the need for less gear, stall, street manners, reliability etc.. but not power.
And yes increasing stroke dont give you anything power wise. Bore is, if you take everything to it limits. A 318/360/340 are relatively in bore size so have similar power potential. A 273 would have a hard time keeping up since valve size will be limiting compared to its bigger brothers. Thats why bore size is the limit cause it limits valve size which limits head flow which limits etc..
A 4.07" bore is gonna have the ability to flow the same amount of air no matter the stroke.
So a 4.07" x 3.31" = 345 4.07" x 4" = 416
A 345 is 83 % of a 416 but a 416 only can spin about 83 % of a 345 of similar rotating assemblies. Which all equals out.
Eg. 345 x 6500 rpm = 650 cfm
416 x 5400 rpm = 650 cfm
Same air flow same power potential.
What about torque you say ?
416 will need about 83% of the gear as the 345 torque or more accurately hp to the tires will be the same and similar mph. Allowing the car to accelerate at similar rate. E.T.
