Default Bitting the bullet again

Lot of you Know I built a new motor for my 86 about a year ago.

I has ben a pain In you know what.

But after working most of the bugs out of it I still fighting transmission problems.
I have a new trans on the way so I started to pull the trans out getting evrything ready for it I also still have a oil leak that I tought was comming from the rear of the motor.

I also found out when pulling the trans the converter they said they put in the car is not the one I paid for thats a whole diffrent story.

The oil leak from the timing cover just spreading to the rear of the motor.

So as long as I have to pull the front of the motor apart I am going to put a hotter cam in it the one in there now is a Howards 214/214 .447 /.477 lift at 290/290 Duration with 111 CL.

I also have 195 Trick flow heads and 22# injectors with 9.75 to 1 compression.
307 rrar end.

Edenbrock Hi Flow intake and SPL runners.

I was thinking to go with a LPE 219/219 Cam I read with a good tune It should pass smog.

Or is there a better choice fo a new cam if so what I need to pass CA smog laws.
I looked at the LT4 and the ZZ9 I just dont want to make anouther mistake get this combo right aagin.

I also just order a new set of CC full roller rockers Steel I want to get rid of my CMH brand rockers.

I know I have to change springs for the extra lift of a hotter cam do the swap from flat tappet to a roller cam at least I dont have to worry about using Zinc in my oil with a roller cam.

Ater the motor rebuild I felt the motor was weak off the bottem I know the trans did not have enough stall to it the guy told me I had a 2200 stall but I think more like a 1600 what still is the best with a 219/219 cam is 2500 stall enough.

and will the 219/219 be a good working combo for me it a DD for now.

I would ask questions like...When you recommend a cam for me, how often will I need to replace springs. And, whether you want more low-mid power or more top-end. Do you know if/where your TFS heads stall? How much lift can your springs take?

The springs I have now are rated for .480 lift the new can somthing like .520 of lift thtas why I have to up grade the springs.

The 219 should give me all around power copaired to the cam I have in there now gong from flat to roller type cam the big plus for me is not have to use zinc in the oil with a roller cam.

On the other fourm they are telling me dont change the cam just put a good trans in with a good conveter then I should be a lot happyer with the set up.

But I hate to spend $450.00 for a custom made chip just to find out It still not what I am looking for.

I have a performance chip now not a custom chip.

I wish I knew where to get a good custom chip for less money I still think $450.00 is high in price.

The set up I been running make the car feel Lazy not what it should do.

Get in touch with Mick (mseven) his prices are less than that and he will hook you up with a custom mail order tune. It will require you doing some data logging so you might have to invest in a cable and the adapter to adapt the chip to your prom.

You need a different convertor BUT you hat to spend $450 for a tune? Those two aren't related.

I ordered a Lunati 60101 It anouther flat tappet for the money I stay with a flat tappet.

I can reuse the push rods LOL.

And I will be able to use the chip it for now I hope.

It makes a little more power not alot more but I has the mean sound to it and it works with in my RPM range where I what the motor to be running at.

It not a race car but a DD for now.

I had to go the next size up Valve springs extra $70.00

So it cost me for now $270.00 to get where I want it instead of $1300.00.

Heres a U tube video what sold me on the sound alone Plus I think I shouild pass smog with a good tune.

I have a new trans and conveter 2500 Stall on it way I figure as long it on jack stands fix the oil leak comming from the timming cover If I have pull the front of the motor apart might as well change out the cam.

If I goining get a custom chip made might as well now get the cam I want I never be thrilled about the cam it the motor after the drive I did not like car ran it not what I wanted.
