yes that is a beautiful setup.....just costs more the most motors. Like say a GMPP LSX454 to put it on....or 2 LS3's.

Not really, intake is $600 and four new carbs are $13-1400. So only around $2k for the main components- just need linkage, filters, and fuel lines to be complete. Way cheaper than 8 stack EFI with 100% of the performance. Other than cold start ups, the IR intake/Dellorto carbs on my VW run as smooth as the LS2 in my sisters TBSS and have 1000x better throttle response. The two minutes of running smooth at start up isn't worth spending 2k+ more for EFI. It's an old truck, it's supposed to have some quirks!

I'm going to make my own linkage and the filter will be in the hood... Going to make an air box in the hood to seal down on the carbs.

I guess I was looking at the wrong one then. I could see the carb's being cheaper then a efi setup...but $13k vs $2500 is a big difference. The Borla setup is almost $13k and I thought the Inglese was too.

[jcramsey]

Wow...can't wait to see how that engine turns out with that intake and those carbs. Very interested in how it will perform!

[jhrusk]

very cool

[pdxhall]

I'm glad you're able to get back to work on the truck. I've been patiently waiting.

[El Campo]

I like the way you are thinking with the intake etc! Will be anxiously waiting to see it.

[Frizzle Fry]

IR intakes (EFI or Carb'd) are cool as hell!

[JR25]

I definitely want to see this in person! I have a No Limit rack on my 55 with the solid front axle. Their craftsmanship seems to be good, dont have the truck on the road yet, so I cant comment on how well this particular rack performs.

How far are you from the mall? I work at the old Lowes building across the street from there. (Active duty with the National Guard)

Yeah the EFI cost is crazy! I couldn't afford that, and wouldn't want it if I could. I can't adjust/tune efi with a screwdriver and wrench.

You and me both, I have dual two barrels on IR intakes on my 90 HP '64 VW bug and the throttle response in 1-2 gears is near violent! I can't imagine what it would be like with 500+ hp!

Yes they are! Not only looks but they perform soooo much better.

We're right off 28 bypass behind Westside High. Come over some time and take a look! You might know my brother Chris Glenn, he's in the Guards.

[theastronaut]

The No Limit Rack came today, looks to be a very well thought out kit. Next purchase will probably be the intake; definitely want to get my hands on one of those while they're availble. I imagine they're a pretty low production part so I'm worried about how long they'll be available.





Also bought another cluster to restore/flip. These things are addictive!

[duallyjams]

But you make the cluster resto look easy.

[theastronaut]

Just threw the rack kit on to check clearances... there's not enough room to raise the crossmember 1.5" like I'd wanted to unless I can find a smaller harmonic balancer. The only other option would be to raise the engine, but that would mean swapping to a high hump floor. I really don't want to raise the engine up since that would raise the center of gravity. I can't move the engine back any farther to get the pulley behind the rack either; it's already against the firewall pretty tightly. Anyone know of a smaller diameter balancer?


I know the rack is in crooked, forgot the donut bushing to center it in the passenger side mount.

[duallyjams]

That's hot rodding, one thing leads to another, changing to smaller one going to change the ratio of all the accessories and moving the engine forward will give you unwanted nose weight. With your skills move the fire wall and move the engine back, I know you didn't plan on doing it but you can do it.

[theastronaut]

I did some more looking around and found a chart that shows the depth of different factory pulleys. Vette balancers only stick out from the front cover 2 1/8", that may be enough to get it behind the rack. The one that's on it now isn't seated all the way either, I'll measure and see if a Vette balancer will fit.

If the vette balancer works let me know, I have a new Trick Flow that I can not use, I threw away the box. 150.00 and its yours.

[JR25]

The hardest part of rebuilding my engine that I ran into was pulleys! But at least you have a thousand options with your engine! Look on Summit Racing, and have fun!

Appreciate the offer! I found a 6.2" diameter 25% underdrive balancer that should fit.

Yeah there is so much available for the LS engines, I'm used to VW's where they've mostly been using the same aftermarket parts for 10-15+ years!

[theastronaut]

Found a vid of a LS3 crate engine with IR EFI. They haven't tuned it yet so it won't idle, but the throttle response and sound is ridiculous!

Driftworks V8 AE86 Moves for the first time -...

[LoRollinLS]

that thing sounds nutz! can't wait to hear it in your truck!

[TommyDuncan]

I used to work at a high end engine shop. We built mostly trophy truck engines which have almost no rules engine wise, other than they have to be naturally aspirated and no nitrous.
We mostly built big, injected small blocks. Usually around 430 cubic inches and 850 horsepower. They actually had to tune some of the throttle response out of them for driveability reasons. Getting knocked around flying through the desert made it hard to ease the throttle...
ironically these engines almost always made a tad more power on the dyno with a carburetor. In a drag race the injected motor would probably win though.
We also built a few IR injected all aluminum FE big blocks for brand new Shelby Cobras. One was 500+cid(I think it was a 513... been a few years) with a belt driven supercharger.

I moved the frame into the shop after work today to get started on raising the crossmember 1.5". First order of business was to do some housekeeping.








With the critters exiled, I layed out a rough cut line. I don't like that I'm going to lose the upper two mounting points above the upper control arm studs. Gotta find a way around that. This is with the frame flipped upside down, they're the bottom two holes. They'll be right at the upper frame flange, and there's no way to relocate the hole in the crossmember any lower. I do want to drop the upper control arm studs .5" for a better camber curve, so that may drop the holes back down into the side of the frame rails. I might be able to squeeze a couple smaller diameter bolts in there then, but it would be super close.

I'm also thinking about dropping the lower rail (upper in pic) 1.5", then cutting out the whole center of the frame rail and filling it with flat plate so I can make clean mounting holes. There's no way to cut 1.5" out without butchering the holes like I have layed out here. I'd rather just section the crossmember itself, but then the R&P mount wouldn't fit.

John, I sent you a PM response. From you pic, those upper to holes should end up completely above the top flange of the frame rail on yours. If so, weld on a "tab" to run the bolts thru or weld on a couple of threaed blocks for a bit a a cleaner look.

I've always heard that drag racing VW engines made more peak hp with carbs vs EFI. Carbs are able to better atomize the fuel at WOT, I think.

[theastronaut]

Got the frame on a cart so I can move it by myself, and I'm not working on the floor anymore. Made filler plates for the drop section, welded them in, then smoothed the welds. Should get to do the other side tomorrow. I ordered 5/32" plate from McMaster Carr to fill in the blank spots, nobody locally had that size.
