Ok...
Here's my plan..

With my current meager bolt-ons I'll give myself a starting Hp of ~300 maybe 310

Inhale:
Port and Polish the TB

Exhale:
JBA or other shorty headers
Yeah Yeah I know...but its not going to change and until someone can tell me a way to install long-tubes and pass smog in California..legally shorties it is
Shorty haters back off

Custom True Dual exaust system with over the axle into a double in double out Dymomax Ultra flow muffler out back

Internals:
OldMan or 224/224 cam 114 or maybe 112 LSA depending on who I can get to do the tune

External boltons:
Underdrive pulley

Drive train:
TA Rear cover
3.90 / 3.73 gears..again.. 4.10's are the drag racer way to go..but I aint drag racing and I don't want to run the tolerances that close..Im keeping my 10 bolt

Tune the **** outta the mother...Then drive it like I stole it!

My choosing NOT to go the heads and cam route just yet..I really don't need the HP nor do I need the maintenance headaches..mostly I want to drive the car Vs constantly wrenching on it

Who wants to guess my final HP rating

 

Sounds good, sucks that you have to run shorties though.

You didn't mention cats. I would assume if you have to run shorties then you sure as hell would have to run cats.

I think you could potentially squeeze as much as 370-380 out of it as long as the cam and tune are quality.

 

if we guess the hp right do we get a free antenna?

372 is my guess

 

You should be in the 370 range. I'm gettin the 224/224 .581/.581 114 cam & 918 springs in soon also. Heard nothing but good things about it.

 

Here's thought:

3.90s aren't available for a 10 bolt, so 3.73s it is. Looking into get them mikronited (polished).

A single pattern is not the ideal stock manifold cam. A TR CheatTR on steroids is the direction I'd go if you want high rpms; if you want lots of low end torque, look at something similar to my cam.

You can get around 370 HP and have good torque too.

 

Hey mike...whats up!

Yeah..why not!

 

I havent researched it yet..but someone tolde me that Arburn made 3.90's for teh ten bolt that didnt whine.

Will this pass CA emissions?
As for a cam..Im looking for roll on acceleration..at speeds between say 40 and 70 ...not top end

See the problem is Im spoiled from riding a motorcycle....its all about turning and acceleration

 

Free antenna to the closest person..

 

I think that is where it's at. I have tjhought about dumping my cam and getting the cheaTR.

 

It's -8 overlap at .05 so it should with a decent tune. -4 overlap is considered safe. With a really good tune, 0 can pass.

As for 40 -70 mph power, what gear? 2, 3, 4, or 5? It's easier to think in terms of rpm range when picking a cam.

 

Sure how about between 2500/3000 and 5K

 

Good luck on the build dude ......its good to have my 'puter back

 

if i were you i would go with the CheatR cam because of your exhaust restriction however it sounds like you have a nice build going on, let us know the final numbers

 

Exaust restriction..a dual-with a cross over Im thinking is a pretty free flowing exaust..unless Im really off base

 

I think by exhaust restriction he is referring to the shorties

 

First off congradulations on setting up a plan! That's the best way to mod whichever direction you decide to go...

Second, shorties with high flow cats and true duals are going to be a pretty good flowing system. It's just not going to have that scavenging component of long tubes, but free flowing, no problem there. I pulled 344 rwhp 350 rwtq with shorties and all the boltons with my JBA true dual system

As far as cam, have you considered the good ole Comp 216/220 114 lsa? It's what I'm probably going to run in an auto with no converter. Been shown to put down over ~370 rwhp itself and over 400 with heads. Pretty good for such a small cam.

I think the CheatTR cam is too exhaust biased for shorties. Remember shorties aren't exhaust logs like stock manifolds, they flow pretty well because of the individual primaries. Something closer to the bias of the 216/220 will be better imo, and don't overlook single pattern cams like 224/224 114 lsa. They make hella good tq all around and good top end too. But they just give up some off-idle tq, somethings you could regain with a nice single pattern 220/220 114 lsa.

All the cams in this range are going to be similar, I would guess around 370-380 rwhp.

And as far as gears go, 3.73 is a great gear. I had a 4.10 and it was a bit much for normal driving, I was shifting and skipping gears all the time! Also, with true duals, you are going to have more midrange tq, so you can pull through those 3.73s very nicely.

 

Thanks LSx24..

Im going to have to go to school when it come to cams....

As I stated above..Im looking for mid range torque and acceleration, not top end speed


BTW..I also went to your site..we have a lot in common

I have this sickness as well

 

My cam would do the trick. Might fine tune it a bit and push it a little more with a 214 lobe if you have high flow cats. 214/222 112 110 will give you a very solid 3000 - 5000 rpm band. Will show improvement at 2500; shift at 6000 - 6200 rpm. You'll give up power above 5800 compared to cams such as a CheaTR or other wide LSA cams with later IVC's.

 

110 LSA...dose it idle?

 

112 is the LSA. It is advanced 2 degrees so the intake centerline is 110. I didn't change my idle speed from stock with mine and it sounds pretty close to stock since I have a full stock exhaust. 214/222 112 is still a small cam. overlap is -6 at .05 and it is on fast ramps. It has less overlap than a 224/224 114 cam.
