2.5 inch pipe off truck manifolds to 2.25 crossover in front hugging and routing in front/below balancer then merge into 2.5 up to flange

Found a very nicely cnc cut mild steel flange on ebay that is machined for 2.5 or whatever size pipe you want to use.... it will fit up nicely

I got much of the pipe laying around we can use for this. I can already see we are gonna have to lose the hood latch for the 3 inch core intercooler to fit.

We only went with it because it was the same price as the 302-2 pan, but my understanding is that this pan would would with a 4.00 stroke unlike the other holley pans.

I don't have a tig welder setup "yet" so it saved some $$ and time not having to have fittings welded on etc..

3 Window - I was just planning on using a NPT 1/2 inch barb fitting and budget rubber hose for the drain this time... as long as we can get the downward slope right don't think a 90 will be needed

This engine is pretty tight against the firewall... ALOT tighter than in my Nova. We are going to have to do some clearancing... I am trying to convince him to let me modify the crossmember so we can get this thing forward at least 1/2 to 1 inch.

LOL see how tight the cam position sensor is ? Might be able to get it connected by removing the sensor, installing harness connector, then re installing... or using a big hammer to firewall

also when I set the intake on the stock truck fuel rails are really close ...

Started last night on the hotside using stock truck manifolds flipped forward...

in mock up it was obvious we will be cutting the flanges off and melding them with 2.25 or 2.5 pipe for the crossovers and eventual merge


scrap pipe collection I will be using


chop chop


passenger side had some big clearance issues so doing some cutting and melding



This will be blended all together for the passenger side crossover

Started the welding and fab part of the hotside...

this is all using stuff I had laying around

Driverside manifold


Passenger side manifold modified

not 100% happy with this side and may start over and route it below thermostat outlet etc so we have more room to work to the merge...

we leak tested everything and it was good to go

welds better on this one as there weren't any inconsistent areas to fill
4 inch ebay flex pipe that has the solid steel inside


coming along

Changed my mind on 1 piece and got a good idea on the rest... Kind of embarassed about the welds on the passenger side manifold ... too many gaps that I tried to fill in and things got sloppy

Gonna run 2.5 inch expander from the flex joint and set turbo placement then make a nice merge from the passenger side somewhere into the 2.5 allowing for enough room to do wastegate too

Hotside progress

Figured out the turbo placement to retain the inner fenders and welded it up


made the merge for the crossover


mocked up the rest of the hotside crossover... when finalized, I will weld in a 2.25 v band on the 45 degree bend before and coming into the merge piece


Gotta think about wastegate placement... maybe somewhere on the housing, maybe somewhere else

Worked a bit this weekend




ugly but it will hold and make boost lol


Hotside is done



this will all get heat wrapped


intercooler mocked up and starting some cutting for the coldside to fit



The wiring harness will be here soon from PSI and I can get going on that.

The fuel system is about worked out as well

Those more experienced than myself... how is this existing sump to the tank ? Will it work OK with inline pump + efi... seems smallish, but if he always keeps fuel topped off should be ok?


made this modification for the return


pure budget is a concern.... I think welding and doing a different than existing sump on here will cost more than just buying a 100.00 fuel cell that is already sumped... Car owner doesn't want to lose existing tank though.

So what do yall think?

Same mod as I did to my tank, but instead mod a 5th gen hat to house two 450 pumps with a hobs switch.
