[hifi875]

Dang it I am computer illiterate!!!

what tranny are you running?? also, what did you do for fuel system? Im getting ready for this same exact swap..

[hifi875]

i am running a 2004r and my fuel system consist of holley 125gph pump (external) and corvette fuel filter.

[hifi875]

all ive got left is to change my accelerator pump on my carb and finish up my timing/map curve. It is a very smooth motor that makes some decent power it seems

[WS6]

very clean. I like how you did your steam lines. Congrats on getting it done.

[hifi875]

thxs, the guy who did the work was very detailed in everything. i did do some of the work, but very little. it is amazing how long it takes

What kind of A/C compressor and mout are you using?

[hifi875]

sanden sd7 and vintage air mount that adapts to the factory corvette compressor bracket. at first it still stuck out too far and it the mounting bosses were cut down a 1/2 inch (i believe) to tuck it in to the block.

[colt zantop]

lookin good...I like that clean look!

[hifi875]

thxs man appreciate it just trying to keep up w the joneses

i hear a zo6 cam inst very friendly when it comes to carb tuning. there was a thread about it on ls1tech

[hifi875]

yeah ive heard it both ways, not going to do it until i get some milled z06heads to go with it. it does very well w/the ls1 cam in now.

[DCx]

i have a carbed ls1 as well. very fun stuff.

Looks good! What headers/oil pan are you using? Are those BRP mounts? Any pictures of the underneath? Curious about exhaust/oil pan clearance.

Looks nice. I like how you did the coolant by-pass lines. What Corvette filter are you using?

I am anxious to hear how the z06 cam performs in the 5.3 (hp wise) does it still sound stock? Also, why are you going to zo6 heads ? The 5.3 heads give you a better compression ratio than the LS1 / LS6 heads do. Does milling them bring the CR back in line?

LS6 heads have better flowing ports. They are not the same as LS1 heads. LS6 heads > 5.3L heads

I am going ahead with pro-touring my 1969 Camaro RS Yenko tribute.

[hifi875]

i am running the complete brp setup minus crossmember. motor sits up alittle but i like running the fact corvette accessory system. the ls1 cam in it is very smooth sounds like a truck motor w/headers and exhaust, very docile at idle but when u nail it it comes alive

[Ratty 46]

Nice job ..... looks right at home.

Nice...how does the power feel compared to your 413sbc??

[hifi875]

it doesnt have the low end grunt but it pulls hard on the top end very well, the 413 was good till 5500 this thing pulls to 6500 so its a different feel my 3.42 gears may be alittle high for this motor but i dont want to change gears. 342 is a great compromise in driveability and performance
