well, what do you think? it's been bored .040 over and the decks on both heads and block have been zerod, looking at just under 10:1 compression, runs very strong.

 

next

 

...

 

me working my butt off trying to get it done before homecoming dance (ended up breaking the flywheel later on the way to take my date home, needless to say, i was embarassed)

 

and the blowed up motor....the two motors at the top of the pic are a (left) 305 and (right) 350, the 350 is mine, i just don't have the money to do anything with it right now...

 

damn im about to wet my pants! very nice work. that is a sweet lookin motor. now i finally got some competition.

 

i also had my block zero decked. mines only runnin about 9:20 to 1 comp. my blocks also bored .040 over. i thin every little bit helps. keep me informed on what you run ni the 1/4. also what size valves do you have in there? what are your cam specs

 

right now, the cam and valves are stock specs, i don't think i will spend anymore money on this motor. i have spent alot of time and almost $3000 on this motor rebuild and i still want more horsepower. like i said, the 350 in that pic is mine, all i have to do if find a transmission. then i will build a 10:1 355 with a 750 holley vacuum secondary on top with at least a .490 lift cam.

 

ah i see. i have put over $1800 into my motor alone. i really have no interest in swapping to a 350 though. none the less great job on the rebuild. its a beautiful motor.

 

What paint have you used on the intake set up?
How was it prepped before the painting?

 

Damn, it looks good...

 

nicely done!
my bro has a 91 firebird actually, he's going to rebuild his engine...for more power of course.

 

intake manifold was painted using regular black engine paint. all i did before i painted it was i cleaned it using an engine degreaser. thanks for the copmliments guys, i worked very hard on it. i also changed the 2.8 badge to 2.9...which was done just for kicks and grins...

 

Looks good.

Heh, I'm probably gonna paint my 3.4 block red also. I think I'll also paint the intake and plenum red.....PLUS, I have fiero valve covers which I already repainted red.

Hey, at least it'll match my interior.

 

have you had the motor runnin yet? if so does it feel very strong? is it faster that your previous motor.

 

yes, the motor has been running, it is very strong on the top end, pulls like a horse, but is stubborn like donkey on low end. i think that the stock cam and the slightly bigger bore/compression boost don't like each other very much on the low end, but man, 80-100 is soo easy in this car now, any where above 3500 and this beast pulls like a ****...

 

Any of you guys have a double roller timing chain? If yes, do did you have to modify the timing plate. I want to have my engine rebuilt. These are the things I plan on adding:


Double roller timing chain
9.5:1 compression pistions
Crane CompuCam 2030
Comp Cams 1.52 roller rockers
Bored Block .030 over
3 angle valve job
port and polish

and any parts neccesary for the rebuild.

I keeping the motor naturally aspirated and I am only planning on rebuilding the engine for maximum efficience instead of performance. I use my car for driving around. I like to cruise at a comfortable speed (55 mph) while listening to music.





Anyways, that is a nice looking 2.8l rebuild.

 

I have often wondered if the 2020 cam might be a better choice. It is made to increase H.P. in the lower ranges.

Seems a better choice for a daily driver.

 

The Crane made cam is almost what is used in the 3.4 engine.
It's a great choice

 

3000 ouch, how much HP you end up with??? a crate 3.4 is only 2000 165-175 hp some mods get 200 add 150 NOS shot and 350hp later tires are flyin off the rim

 

Need headers? Have some... Never used..

 

nope, thanks anyways, i want my 350, now. the $3000 was a little high of an estimate. That price contains a tranny rebuild also that happened this year. i am just tired of doing all of this work and spending lots of money and only getting halfway there on horsepower. i am going to put the 350 on the engine stand tomorrow if my dad lets me so that i can start taking it apart to begin the rebuild. if anyone knows of a place that i can buy a tranny for cheap or get a th350 case in the middle georgia area that would be great...
