opinions on 428 sbc for mod

[charlie115]

thinking about going a different route this year. wanting to build a 428 sbc flat top 76cc head, small cam, kinda like the create cam, hydrolic. want to run tms track in the spring, 3/8 small bank, sweeping corners. goes dryslick fast. any thoughts? will also run on 1/4 mile small bank sweeping corner track.

[Confused?]

Just curious, but why are you wanting such a big motor if you plan on low compression and small cam? It would be much less expensive to build a mild 355 or 383. JMO

heat races are tacky and fast thus big motor. but for the dry I wanted to take the instant power away. I may be thinking about this all wrong.

When you say TMS, do you mean the dirt track @ TX motorspeedway in Ft. Worth?

[charlie115]

yes. ive heard its a dryslick nightmare

[charlie115]

yes that's the track. built a new shaw to run there. haven't run the track before. just wanting to try something different.

Been several years since we were there and that was with a late model. But along the lines of what Confused posted above, think about what you are building. Myself I would get the compression up to at least 14:1 and go with a roller cam. OR if the slick part is a real concern then go down in cubic inch size.

The old saying is "there is a horse for every course" is very true.You can't build an engine for a 1/2 mile hammer down racetrack and expect it to hook up on a slick 1/4 mile.At some point you have to work on setup and driving.
Features are what pays the money.Its nice to set on the pole but finishing 18th or 20th won't pay the bills.I have had little steel head engines that would not qualify good against the all aluminum engines but come feature time they were out to lunch.

I have a 14 to 1 388 but when its slick it hard to keep tires under it even with a good right foot. set ups im not too worried about. new car, im sure keven at shaw wont steer me wrong. so now im at the motor. just worried about the slick I guess.

[LateModel B23]

Myself, before spending the money to build a 428 as you describe, I would stick with the 388 and work with gearing and setup. That is just my opinion though.

thanks b23

Stocky Boy can't keep a consistent time ill say that and you can't deny the watch little buddy. But that's not apart of his set up routine. 👍

I like the 428 idea, how about the option of putting a 2bbl on it when you wanna knock off a 100-150 +hp or so.
Worked perfectly on our 14* roller 406 on a bone dry dusty 3/8 day 2 of a big show.

Easy to take some power away when you need it, hard to add when needed!

[charlie115]

I had john at jdr build me a 2 bbl this summer. you would be impressed with what that thing will do. what do you think would make a good set of heads for this build? maybe vortecs or open chamber darts?

[LateModel B23]

If I may ask. What rules and where are you going to run weekly? IF you are running weekly that is.
