4th Gen BBC Project
They are Lemons headers for stock heads on a BMR k-member. The car obviously isn't mine so I don't know the orientation of the plugs. I've thought about using Lemons, but since my heads aren't the same as stock I'm afraid to drop $1,200 for a set that probably won't work. I'm going to cut the tubes that cause fitment issues on my car and then take it to a shop and see if they can re-route them to work. I have an idea of what shape they need to be so I might try to the ship/return route and just order a few pairs from Summit and see if anything works and return the ones that don't.
The shock towers aren't the main issue, it's getting them to go straight down on the passenger side and having them swept back on the drivers side. Both sides have to tuck pretty hard as well to make it by the k-member and tunnel which of course puts it really close to the starter, pan and oil filter.

I figured if the Comp's for a GenII are close, the Super Comps should not be too far off, right?

That would be a good idea to gain a little more access to get to the spark plugs on the passenger side!
So many variables when you're dealing with non-stock components. Difference's in heads, k-member, starter type, plug angle, etc. make everyone's needs a little different. LS1 Tech Stories

I was looking at possibly increasing the size of the primaries, (what are the 2455's, like 2"?) so that is what made me look at alternatives.
make sure and drop the motor down a bit... my valve covers are no where near the cowl... and yes for that a custom set of headers is mandatory since it will be around 2.25 primaries... make sure you can take them apart and i'd have them exit through the front quarter to help with clearance.
What size engine do you plan on running if it is a tall deck? Like a 572 or 632 or something?
I am not at either of those sizes, but I can tell you that unless the car is backhalfed, you will have a hard time hooking on marginal tracks without a Procharger, let alone with one. Also, if you are not running a large tire, plan on changing them regularly.

No need to backhalf it and run a large tire either, it's all about power management. My car is a 25.2 setup with all custom suspension to run the 275 DR class and plenty of turbo and N20 guys making it work running as low as mid 7's, but your right, the track has to be working...
That is what my car has as well and we had to do a little clearancing on the firewall to make that work. They have worked fine and you can't beat the price!

I'm going to try the 2454's and see how those work out. Also for anyone interested, the Hedman 608090 (I think that's the part#) clear, but they are too short, the collector actually hits the k-member, so you have to cut straight across the tubes and weld in some extensions to get the primaries long enough.
Little update. The car is together and I was trying to get it to start before I send it off to get tuned so I at least know that everything works. The problem is that I can't get the dang thing to start. I have fuel pressure and spark but I guess the base tune the BS3 came with is way off.
Next, I've decided to go ahead and can this project. After getting it all together this thing is a HUGE PITA to work on and when it's all said and done it will still just be an old Trans Am. I'm still going to get it started and get some numbers out of it since I've put all the work into it, esp. wiring everything up and then I'll pull the motor/trans and put it in my 67 C10.
I'm going to pull the LT1 out of the C10 and either try to sell it all together or make it into a road race car or something. Not sure yet. I also just moved and I don't have internet yet so once I get it hooked up I'll post pics of the T/A almost done and the truck it's going into.

i know your disgusted with the car... everyone that builds one themselves gets that way... all racecars are a pain in the ***.... get it running and take it down the track a few times... you'll feel better....
i was just as pissed as you about 6 months ago... believe me.

I kind of understand where you are coming from, but at least yours is close to done. Mine is looking like it is going to be a 5+ year project just to get it running.
I have a sale pending on my 441. If it goes thru the BBC install is back on for me.
I plan to do a pump gas 632 with a little spray.
This thread is AWESOME!! And the car is looking Great!!
Definately inspiring!

Ok, here are some cell phone pics from this weekend. It's all I got since I don't have internet at home.
Here are the pics of my old truck that it's going into once it's been tuned.
A lot more room

There isn't much more room. It's very hard to install the intake because of the fuel rails. There is no room at all between the rails and the cowl. If I want to pull the rails to check the injectors to see if any are leaking and to make sure they are all working correctly I have to unbolt the cradle and lift the chassis up with a hoist so I have room to lift the rail.
That sucks.
My cowl will be gone though, will have a front mount distributor too. I have a shorter valve cover and think i might lower the engine a little too. you have a pic of the bottom? like to see your pan setup and clearance..

Here are pictures of the pan and motor mounts with no cradle, but there is no clearance issues with the pan. The steering rack is the closest thing to the pan, which is about a 1/4 away.
