Single To Compound Thoughts

[Corkey]

I have reviewed several threads, pages, and research over the past week.

I'll be the first to admit that I am unfamiliar with the setups and power possibilities, hints as to why I am asking for some knowledge.

The whole buy once has been my theory, but I have yet to understand the jargon, LOL.

From the outside looking in, I see twice the amount of money for parts, which creates twice the amount of power/power band.

After we seek mods that require revisions from the doc, we get the thrill of feeling what is capable of the motor; for me, it's my addiction.

It leaves me to sit on my chair and tally up what build I can create and cry on the total cost...

From DDP S464\S480 kit (claiming, I believe, up to 1050hp)

Swap out to 625's from 425's

12M exergy CP3.

BBI Stage 3 injectors.

D&J X beam rods. (I'm not sure about the stock length vs. the other.)

D&J stage 1 or 2 head (comes fully assembled with goodies I added)

It's North of 21k without labor.

From the current setup to this possibility, there should be a screaming difference.

From a targeted power goal of 700 to 1,000hp, I know the LP for the 68 will need to jump up; I will probably toss a Sonax drum in and Revmax VB.

I'm curious if this concoction is way overthought or if I can hit those goals with money to be saved.

The build wouldn't start until December or Jan.

This is why I'm gathering information now to decipher which direction to go.

A single S468 and some bigger injectors would easily get you to the low side of your power goal without changing anything else.

If you still want to turn it up from there, you could keep the S468 on the manifold, add the S480, and do all the other work you mentioned.

I wouldn’t even think about a Sonnax drum north of 700 hp.

For anything over 900 hp, you need the 12xr setup from Revmax.

I like wagler street fighter rods over the x beams, a lot cheaper and rated to 1500hp.

Plenty of guys on stock cylinder heads at or slightly under 1000hp with upgraded springs and pushrods of course.

I wouldn’t upgrade a head unless it was needed due to cracks or upgrading to a ported head with the intake shelf cut off for a side draft intake. Yes you can put bigger valves but you are still limited to port size.

Id also talk to someone at s&s or ddp injectors over the bbis for over 1000 hp. I personally think ddp makes the best injector for anything over 200%

I’m working towards compounds on my truck once I have time and a good excuse to pull the motor for rods and a girdle I’m planning on s467 s485 side by side kit with 250% over injectors.

My only concern is the 700 mark, I would feel comfortable with reassuring upgraded rods will take the abuse.

The compounds put a hell of a torque strain on the rods, given fuel upgrades and twice the air compressing.

I have been a diehard single person for years, just thinking of a change in a build for once.

I was eye balling a few North River boats, but it would get more use of the money in the truck.

As far as the locations, what are the differences on the over and under vs side by side.

Greg A threw a side by side I believe on his dually with having to modify a few things to fit?

I haven’t seen Greg a’s haven’t been keeping up with the YouTube guy as much. But yes have to get rid of the second battery. I did that awhile back and got one good battery.

For 700hp I’d save the money and stay with a s467 with added fuel. Get a stock stall triple disc torque converter maybe some gears if you are on bigger tires and it will spool quick and be fun to drive.

I got the goodies and triple converter.

Still on stock 3.73's, thought of going 4.11's, probably nitro.

I haven't been a 467 with heavy fueling, assuming it'll pin you back a little.

10M CP3 and a solid set of injectors with push rods & springs is what I would need.

Around 8k for new everything

Exergy, S&S, Hamilton's, revision

Its 60% cheaper than the compounds.

Knowing the additional strain on the internals would keep me from going compounds...really just depends on how much you wanna spend....if you don't care then hell snag up a wagler street fighter block and some huge injectors with turbos of choice and go with it....are you just chasing HP goals or do you tow with it?

If you spend a little bit more now going big on the fuel you wont have to worry about doing it over again in the future, if you do decide to go with a big 1,000HP set up.

I'd go at least a 12MM CP3 and 100% overs.

I made that mistake as you can see in my sig.

Completely agree except I’d go atleast 150% really 200% if tuner can work with them. You’ll want 200% to break the 1000hp barrier.

If I do go compounds I’m looking at 250s maybe even 300s but at that point I’ll be shooting for 1300-1600hp kinda depends if I ever finish my race truck or if I end up selling it.

If I do keep it ill stay big single and go s476 with 200s and stay right under 1k hp.

Right now I’m happy with my 467 and 100%s and dual pumps. It will break tires loose almost anytime I want them too and has more power than any normal person should want.
