454 or 427????

[RingMaster4x4]

I have a 454 that I am going to put in my chevelle, but I have been thinking about throwing a 396 crank in it and making it a 427. what do you guys think?

i my self like the big bore short stroke. thay rev up faster. but thay say THERE IS NO REPLACEMENT FOR DISPLACEMENT!!!!!!

I'd go with the 427 personally.

Neither, If you're going to swap cranks go to a 4.25" and make a 496.... "There is no replacement for displacement"

I used to have a 70 chevelle I swapped a 427 into, very fun car. Ran high 11s with a fairly streetable combination, trying to go faster got expensive but more importantly made the car a lot less fun to drive. So here is my logic on going bigger, The bigger cube motors get away with bigger cams and heads, and less compression while maintaining good street manners and you can use them with taller gears tighter converters... You can make a lot of power with a 427, but they start to loose the driveability sooner.
Thats why I have a 540 in my chevelle

That is understandable. I am just looking for fun steetable ride. I want something that I am not afraid to take out and hit the highway, and will knock the door off most people that think they are hot ****.

couldnt agree more my uncle has a 72 Nova w/ a 427 that I drive all the time that ive got into the 10s, 10.97 to be exact, but that thing would be in the low 10s w/ a stroker kit in it

yeah do a 496!!

but I agree... short stroke is awesome for higher revs

I would go with the 427. I wouldn't want a big block stroker in a Chevelle, especially if it has a hard time hooking up. It would seem higher RPM horsepower from a 427 would be more usefull.

not for on the road b/c of higher stall and gears, and I know you have a torque engine w/ your cummins but its pretty clear youve never driven or ridin in a torque monster engine like a 502 thats got heads and a nice cam or something like that b/c if you did youd be sayin stroke it

I have a lot of experience messing with cars. With a big heavy vehicle I would want torque, in a light car more HP would be more benificial, from my experience. I prefer high RPM engines in a car because you have a lot more to work with.
