Gotta completely stock AOD 5.0 LX (1990) and am ready to start buying parts for spring.

It's gonna be a street car, and like everyone else, I want 300RWHP

Here's what I'm thinking:

- Used GT40 P Heads

- E303 or TFS1 cam (advice on this choice?)

- GT40/explorer style upper/lower intake

- 70mm T/B

- Cheapest shortys I can find that'll fit the P heads

- Cheapo Off Road H pipe

And Ima try to pick up a used 6psi blower setup (paxton or powerdyne) I know powerdyne gets a bad rap on here, but I like the simplicity and cheapness.


Whatya think? this should put about 300 to the ground even with an auto? I was thinking so.

Will all the above require a switch to 24lb or better injectors?

I'm planning on trying to find as many used parts as pos. and hopefully spend about 2k. Think that's doable?

Thanks!

i dunno about 2g's, theres alot more you'll need to buy. with a cam you'll need a new valvetrain, period(pushrods, rockers, springs) then you'll need fuel upgrades, atleast 24#s, new pump, afpr would be a good idea. i'd say just find a used blower with more than 6psi, like 9 or 10, then get exhaust.

I know I know

I just cant stand the idea of forcing air through a ****ty top end for some reason.

Good call on the valvetrain. I'm not dead set on 2k, just don't wanna end up with a huge pile of money in this car like I've done with all my others.

Between 2&3k I guess is more realistic. But the closer to 2k the better

lol. i know i had a price set for my car of 5k. i'm right around 8500 now.
damn car ha.

i guess you could do the gt40 h/i and the 6# charger. that should still put you atleast close to your goal. then upgrade the cam/valvetrain later.

Hey there's an idea.

That way I wouldnt have to stress about not having the appropriate 500$ torque converter for my cam profile! HA!

Think the stock cam will be much of a hold back point with a GT40 top end?

If I'll be sacrificing like 30hp It'll bug me to death so I'd rather just spring for a cam etc. while I'm already tearing it apart.

ctgreddy

nah the stock cam is pretty decent actually. just throw the h/i/poweradder on there and have fun.

Alex-7

Thanks for the tips! I like the way you think....


I'll give it a go with the stock cam and see where I get

with bolt on-n and at least 10 psi of boost 300 rwhp is a breeze and you shouldn't have to open up the motor one bit

Alex-7

True but arent more fuel mods required for that much boost? And again, for some reason it bothers me in general to boost through a super restrictive top end.

You think 2k would be better spent on a used Vortech (or similar) and supporting mods set up for 9-10psi, than a used GT40 top end and a used powerdyne (or similar) set up for 6psi?

Which would make more/more useable power?

Stock E7 top end seeing 9psi?

Or

GT40 Top end seeing 6psi?

Just curious.

i would keep the stock cam add some 1.7 rr's
use a gt40 top end, a used vortech with some where around 8-10psi
fuel upgrades
exhaust
and the most important part
A GOOD TUNE
