1987 IROC Camaro Pro-Touring Build

[WSSix]

4th gen drive shaft fit 3rd gens? Should be able to pick one up cheap if so.

You need to be on frrax.com if you're not already. Great site for making fbodies handle.

That looks like a de-coupled TA. That's a serious piece if so. My guess is it was never designed for a T56 only the T5 and 700R4 found in 3rd gens. Honestly, I'd cut the rearward mount off the bottom of the tail housing. Those mounts are were the 4th gen TA mounted to the trans. You could probably slice it at an angle from the side so it doesn't hit the bolt any more and call it done.

LS swap would be my 1st thing to tackle.

I agree but I'm not the best for an unbiased opinion since all my vehicles use an engine from the same engine family...

However IF the current power plant is running well and meeting your needs...

I know an LS definitetly would make a ton of sense on this car! It would be easy to do since it's already set up for fuel injection and the motor mounts, headers, etc are all readily available. I tossed the idea around for a bit but in the end I decided to stick with the ol' small block for a couple of reasons though:

1. Price - I know LS's can be had for pretty cheap but the motor I have is running well and I can save some money but sticking with it. Not saying I can't build a nice LS in the future though!

2 . Uniqueness - I wanted to stick with the small block for now to have something a little different. You don't see too many small blocks anymore, especially with the cool looking Super Ram intake! Once I get it out of the car, resealed and checked over I'm hoping she should run nice and smooth for a while.

Continuing on with the disassembly process despite the 10deg temps here in Mass! My little garage heater is working overtime to keep my work space bearable.

I have the fuel rails and injectors off the car. I'm thinking these are Ford "blue" injectors from the 5.0L Cobra... can anyone help me to confirm that? If so, they are 24lb injectors and I think these might not be sufficient for my 350 if they are flowing correctly. I got the following from onallcylinders.com:

injector size in lbs./hr. = (Max. HP x "Brake Specific Fuel Consumption") / (number of injectors x duty cycle)
So...
Max HP = 350 (estimated)
BSFC = 0.5 (estimation for a modified, naturally aspirated engine)
# of injectors = 8
Duty Cycle = 0.80 (the amount of time injector is open versus the total time between firing events; .80 is safe for an OE injector)

(350 x 0.5) / (8 x 0.8) = 27.34 lbs./hr<-- Looks like I need bigger injectors... any thoughts?

I'd like to send them out to get rebuilt and flow tested as well... any suggestions on who could do this?





I also managed to remove the transmission crossmember and started working on getting the transmission out from under the car. I tried supporting it with my floor jack and a piece of wood, but definitely did not feel comfortable doing it that way. That T56 is heavy! I ended up heading over to Harbor Freight and grabbing a small scissor lift to use. I don't mind buying tools like this if it makes my life easier and I'm going to use it again in the future.

Navigator injectors are blue, Cobra are black...must be some kind of hybrid ��

Your math is correct. They most likely were pushing the injectors harder, meaning a higher duty cycle. Assuming your injectors are 24lb injectors. YOu can safely push injectors to 85 and 90% if necessary. Just depends on what you need, what's available, and what your fuel pressure is.

According to this link https://www.injectorrx.com/bosch-fuel-injectors/ They are 25lb/hr injectors.

They'll work just fine for you. You can always increase the fuel pressure, too. I recommend a dyno tune or at least a dyno session with O2 reading once you get the car together. You may find power but you'll determine if the engine is safe more importantly

In for the build.

Nice to see a Masshole doing something

I'm thinking the same thing Trey. I think I can trim off the bolt hole there and make some room for the bolt head. I believe Spohn makes a T56 crossmember but if I can make this one work then I can save some cash.
I'm also on frrax.com but don't have a build thread.. just using it for research right now. Thanks for the tip though.
