just got new stuff so i just got in the mail pacesetters, cc306, 1.5rr, 25% underdrive, slp air foil, egr and other block offs, 90 elbow to run with the stock SS ram air, i got the push rods and whatever else u need for the new top end and i think injectors, i also got the a/c del plate but i jsut heard u cant have a heater without the a/c i just need the defroster but is this true. a shop will be doing all the work and then doing a dyno tune and some head work on stock heads. i just need to know is there something else i should be doing to this LT1 other then an LS1 swap. im just looking for good rhp to have fun with... also cant post on stuff to buy but im looking for the single cme tip and something that is louder then the stock slp with no cats... this is all on a 97ss im new to all this i also just got the pro 5.0 shifter just any help or nething to stay away from or a must have will help thanks
Don't take this the wrong way but you should stop buying stuff and do some research. Send the underdrive pulley, air foil and bigger? injectors back. Pushrods? How could you know what length you'll need. Did you read the description of the 306 cam? and with 1.5rr...on purpose? I don't mean to be a jerk but use the search function. There is a wealth of information here and some VERY knowledgeable people that I'm sure will be happy to help you.
Its to late to tell ya to slow down. Stop buying NOW. Air foils, under drive pulleys, and 1.5 rockers were just wasted money. You could have had people give them to ya since they aren't worth having. Push rods before measuring, no no. The antique cc306, stay off youtube. Ask ?'s here
An under drive pulley does make more power whether you guys want to believe it or not.
The airfoil, meh.
If the heads havent been off you can use stock length pushrods.
Bigger injectors probably wont be needed.
What stall and / or rear gear are you going to run with that cam?
I would ditch the 1.5s for 1.7s..... those 306 lobes are lazy.

Have you found any 1.7 SA rockers? I looked a few years ago when I was running the stock cam and didn't find any.
I would also keep the U/D pulley. Maybe a few ponies, but more importantly keep the accessory speeds to a sane level when you're trying to wring horsepower out of that cam.

You can ditch the a/c and still have somewhat of a defrost. I left my blower motor in the dash but eliminated the heater core. The motor just blows recirculated air onto the windshield. Obviously it doesn't work as good as heated air from the heater core but it does a surprisingly good job on a 45-50 degree night when it fogs up a bit.

Headers and 4.10 gears with a tune work good for a guy on a budget. If your engine needs internal work for repair then it makes sense to upgrade the cam and related stuff at the same time. Here's a link to a good cam and valvetrain guide:

i have searched for SA 1.7 roller rockers to no avail, only NSA show up...
OP what they are getting at is that cam profile is antiquated! yes you see it working for you but what do you have to compare to? that cam will run 11s but so will a stock cam, it's all about how it helps you get to the 11s would be the key argument.......

I wouldnt use SA rockers in the first place, personally.
That cam is going to be a pile of **** on 1.5s
Does someone have the night off??? No one took aim at the 90* elbow for the SS intake yet lol.
Under drives release a tad of power but if it's a DD with A/C and you run any kind of sound system other then stock I'll take the stock acc drive ratio and 140 amp alt any day. Most other cars and trucks would kill for that kind of idle out put lol. but it does cost power....actual measurable power
Foil....not worth it's weight at a scrap yard. May idle a tad better but that's about the only advantage. releases a whole 1/4hp at 5800???? Never seen an actual pull where they made measurable power other then a variance.

With the higher idle speed he'll be running with that cam, I see no downside to the underdrive pulley.
gregrob, I agree, I wouldn't run SA's at the rpms that cam wants either. I misunderstood since you didn't mention to him what he needs to do for a non-SA setup. and I doubt he picked up that either.
