once the first snow hits im garaging my car for the winter and then the project will begin. Im changing from TBI to Carb, SOOOOOOOOOOO here i go: First thing is all emissions will go no cat, egr, a.i.r., none of that will be left on, ac will be taken out also. so heres my parts list: Holley 650 Double Pumper with Mechanical secondaries, Weiand action plus Stealth manifold, World sportsman 2 64cc heads with 1.250" single springs, 100# @ seat and 1.6 roller rockers, Lunati street master cam with 292 duration and .480" lift, Full length headers and im going to keep the flowmaster cat-back, switching to a posi 3.42 rear end. Also i found a guy on ebay who sells transmissions and he has 700-R4's (i want to keep the overdrive)that are for street-strip use and can handle 400-500 horse, would a 2800 stall be good enough? I know its a 305...im just doing this for ****s and giggles until i get the 4 bolt 350 i have in my garage prepped and then ill just swap all those parts over to that. So any suggestions or maybe things i should change? By the way my car only has 63k on her so im not sure if high mileage would have been a factor for any of that, just to clarify that.

 

Oh yeah, i wasnt saying its going to make 500 horsepower, im just saying what the tranny is rated for, so no flaming for that one please.

 

You'll be under 9:1 static CR, with that much cam you might want more stall. The 350 will like more as well.

 

When I had that cam in my "kicker" motor, I stalled at 3000. I had a little bit more SCR though (for the cam).

I'd match the springs more to the cam. The ones you list sound more like the springs that come on the heads. I had Isky 235-D's with the Lunati. Comp, Crane, Crower, etc all make good springs of comparable spring rates. I'd stay away from K-motion and other no-name springs, like the "Z-28 perforance springs." I'm a firm believer in the fact that the valvle train is no place to skimp around as far as parts quality is concerned.

I'd email the seller and ask for some detailed information as to what its built like to allow it to take that kind of power.

 

3000 stall, alright. So you guys think i should just buy the bare castings and build the heads myself? I have about 40,000 dollars worth of tools to use in my dads garage so whatever i need to do myself, please tell me. Yeah those were the valvetrain components that come in the heads. I just figured that those would be alright to use because the cam is pretty far under the max lift which is .560". So other than that though everything is good, nothing too big or too small?

 

Bare heads are ok. I'd call and see if you could purchase partially assembled like heads and valves. And if you get bare castings, if you have provisions, work them over a little bit. Never seen any WSII heads to know, but I'm sure they could use some help.

Setting aside the valvetrain for the moment being, what makes you chose the Lunati cam?

 

its got the power band im looking for and i havent seen too many people on here with lunati so i figured why not be different, same with the weiand intake, i havent seen too many people here using them. Maybe ill even use an isky cam with the same specs, im not sure yet. Does it look good so far though? Aside from it being "just a 305" how much of a difference in sound am i going to get from that cam? Since im going up over .100" than the broomstick they use to open the valves from the factory.

 

It's a good cam, don't get me wrong. I never really had any issues with mine, for the 3 months my engine ran with it. However, given the nature of the WSII heads, a good dual pattern would probably be in better nature for the combo. The Street Master series cams are decent cams, however, they are older. Vavle train technology has come quite a ways since they were introduced.

Exactly how far do you want to take this "kicker" motor of yours?

Do you have an instant messenger (why whatchajiggit is in my profile)? Posting back and forth is too time consuming, heh.

 

Any recommendations you can make for me? part numbers maybe? I have to go out and get some stuff for work tomorrow but i want to continue this tomorrow.

 

Part numbers depends a lot on how far you want to go with this engine. The varying level of aggressiveness in the camshafts makes just chosing one out of the blue almost impossible.

Try calling up Comp Cams and talking with one of their tech reps. No better to give cam advice than the people who make them.

 

Good combination for a Weiand 142 blower!

 

how much power do you think this would get me over stock, without the blower?

 

Probably slightly better than 1 hp/cu in.

 

Thats sweet, that makes me happy for now

 

if you look on my website, you can see the combo that netted me a 13.03 @ 103mph with a 305.

13.03??? whoa, you've been getting better eh?


a 292 cam with .480 lift? that sounds like a ton of duration for a weenie amount of lift... what gives?
a comp268xe gives that lift at onley 268 duration... wouldn't that be superior? or is that one "more area under the curve"? hmm, food for thought.

I'd try for an edelbrock manifold, performer RPM's are cheap now that the air gap is out, but the RPM is still a wicked manifold.

 

That's cool, that gives me a good idea of what I could run. I have almost exact same setup as you.

 

not really...
