big cubic inches in dragsters?

just curious, how many people are running bigger cubic inches in their dragsters and how hard are they being worked? i would think not hard at all being as light as they are. how often are you going through stuff? (valve train etc)

Depends on the class and how hard your running it.

Bigger dosent mean it will last longer.

I've been looking up a lot of bbf builds for my dragster. I'm just gonna run a stock truck crank, new rods, forged flat tops and solid roller cam with TFS power port 290s. And alcohol. From what I'm reading every night for the last 2 weeks is it will make well over 600 and in a 1750lbs 225 hard tail dragster I don't see a need for more. I should have no problem bracket racing, quick 16's, and 8.90 index.... just what I'm reading.

615 " , car weighs 1900 lbs w/ me in the seat...
Runs mid 4.50's to low .60's in the heat...

Could I back it off and run .70's and .80's ?
Yup... I could....

But where's the fun in that ???

nice. was just wondering, you dont see many big fords out their other then ihra prostock, not that it takes much to get things done.

I'm a Ford guy. If you seen the fleet of vehicles here you'd know what I mean.... lol. Not too many around me running Ford dragsters and I used to race mustangs until I lost everything in a fire last year. I like being a target for the chevysexuals.....

This is one that I found on the Trick flow site using the heads I have. Different cam and higher compression could make a lot more....

If your buying all new stuff I'd consider doing an A460
Headed engine, great potential for future growth.

I had a 528" on with 12:1 compression that made a shade over 900hp.

thats good number? isnt there different A heads? or is it just the different casting production? i remember a guy a few years ago at our local track was running a set of motorsports A head.
