To carguy: I DO NOT know if this is right, but wasn't the entire intake different for the caprices as well? I thought that was the reason they were difficult to modify...

 

unless the castings were the same between the alum and iron heads it would have had to have a different intake manifold. i cant tell you if they were or not but a different head design would definitly determine modability.

 

That's what I thought.

Just wanted someone to confirm.

 

Yes, they were different, the looked nothing like the Camaro LT1... More restrictive, not as responsive to mods. IE, CAI, T body spacers etc...

 

im actually kinda glad we agree on this one. u have me double checkin myself every time i say a motor of same displacement is different

 

lol... its ok... hey, I hit a well-meaning seagul driving home today...well, actually he hit me... took out my potato pasanger window.....

And I put an album up...is that the one I was supposed to do?

~something about being censored..... yada yada

 

looks good man.

i especially like the one with everything openned up. i guess i didnt realize the new vettes still did the reverse thing with the hood.... never gave it much thought

 

Yup, makes it a "sencord by specter" to work on though...

 

I thought I would throw down some more LT1 knowledge

The LT1 that came in the Caprice and Impalla had the iron heads, as already mentioned, as well as a different cam. The cam was geared more towards the torque end and less towards high HP.

 

did you know that some Caprice and Impalla's came with a "smaller" LT1

L99 (4.3L)
A 4.3L version of the LT1, designated the L99, was introduced in 1994 for the Chevrolet Caprice. It was externally identical to the LT1, but the bore was reduced to 3.736" and the stroke to 3.00" (similar to the late sixties Chevrolet 302 used in the first-generation Camaro Z28s). The pistons used in the L99 were the same as the ones used in the Vortec 5000 with the use of 5.94" connecting rods.
Like the LT1, it features sequential fuel injection, reverse cooling, and an optical crank position sensor. Output is 200hp (150kW) and 245lb·ft (332N·m).
Due to its smaller displacement, it provides better fuel economy over the 5.7L LT1.
