Well my bird had been down for over a year now. I have just recently gotten the spirit back to start working on it again. So I have a 91 SC with a 94 SC motor in it. Long story short I bought the rebuilt motor from a member on this forum. Got it put in my car then 500 miles later it started knocking. So I started taking her apart. So here is my plan. I am going to build a 4.2 stoker. If all things go right I will be buying rods, pistons, and crank form a member of the forum here soon. I also am sending out a set of heads to have the works done to. Any ways I going to keep my plans and what parts I have on the bottom of this first post. There is one thing I'm going to need some help on. That is picking the cam and valve train parts.

Wants:
Aluminum SC pulley
Main Girdle
60 or 80 Pound Injectors


Have:
Main Cap Studs
94 SC block
3.5 inch Cold air intake
MP 85mm throttle body
C&L 85mm MAF with pruple tube
MP for 94/95 SC
94/95 blower
March underdrives
Scp 10% aluminum jackshaft pulley
4.2 Crank
Scat Rods
Wisco Pistons

What are your goals power wise. All out? Mild? I would spec your cam out from dalke. He seems to have the most experence with engine builds.

I would say for my power goals I would like to be over 400. This is my play toy so we will see what I can get.

that is going to take more than a 4.2 kit to get there... your going to need almost 18-20psi of boost

Well I do have a few tricks up my sleeve. I also think im going to install a main gridle.

OK so as of right now I have a few questions 1 will a Monara main girdle work just fine on my SC motor after machining the end caps or will I run into oil pan problems. Or is there a better main girdle to use. 2nd if my goal is around 400 hp will the 42 pound injectors be fine or should I just sell them and get something bigger like 60 or 80?

80's..........not sure if 60's are big enough. Then you have wiggle room!

80s would be safer for 400+whp. 60s would be maxed out around 400whp

I figured as much. Just wasnt sure how much 42 pound injectors will really handle.

I was not maxed out on 60s making 421 rwhp so the 60s will work. Keep in mine the bigger injectors are more touchey to tune

So no matter how I look at it I still need to sell my 42 pound injectors and get something bigger.

Thanks Ken. My end goal is probably going with a Whipple 2.3. Do you still think the 60 pounds will be fine?

If your like me you are never satisfied with what you have HP wise. If you think like that do the 80s ;) If you decide to do E85 some day or other mods the 60s will fall short

I do want to be able to run E85 someday. So it looks like it will be 80 pound injectors. So next question. I have a chance to get a cam from one of the guys on here. Is this a good cam for what I want to build

I just can't have something the same as what you have. LOL I think it will be a good cam. I almost have all the parts to start rebuilding the bottom end of the motor.

1 I made just over 400 on 50s and I was below 90% duty cycle.
2 That cam is weak. Not enough lift. Comp Cams have no clue how to make a good can for a SC. Order one from David Dalke.

I agree my cam is not the hottest cam but it does have 600/610 lift. You need a valve train to go with it though. You want power you need a strong cam

Well maybe some one had a recommendation for a cam.

It really depends on what you are looking for in power, what parts you are planning on using, how much you are willing to pay for the valve train parts, valve train work, max RPMS and even highway rpms (rearend gear). Get all of this together and email XR7DAVE and buy from him whatever he tells you to buy. There is probably 2 or 3 people on this forum besides DD that I would trust to spec out a cam for me and they would probably defer and say ask DD.

212 in 212 ex lift is .570 My old cam with 1.73 rockers. Nearly every bolt on at that time. Dalke built the motor and with a MPx (uncoated rotors) at 15% it make 349 rwhp at 16 psi. A 1.7 AR kit at 19 psi made 403.

Ken's old cam - 210 in 220 ex lift is .491/.491

Sissy Sticks!

Ill admit tho, untill this year Ive been running a 206/212 553/562 I believe. Made 540rwhp with it though :p

My cam now is a Comp cam that Dave Dalke installed. It is 224/228 .602/.610 lift I dont remember the overlap. It has an aggressive idle. Like I said there are other bigger cams out there. But I beleive this is a real strong street/strip piece. I do have valve releifs cut in the pistons and I have the yella terra valve train as well. If you want to be a killer strip car I would step up from this one.

The car is going to be a summer driver and strip car. So yea I have plans for big power. For now it will have a 95 blower on it but the end plan is a whipple.
