yeah, i kinda figured i would have the same prob if they sent another set to me. i could have made them work .. but for as much as they cost, i shoudn't have to. besides ... free manifolds and 200$ to get them jet-hot coated .. saved me 700$ .. lol.i'll put it in the car else where i am sure.

I need info on swapping a Pontiac 400 into an 84' Trans Am, what all parts would i need. The 400 has a TH350 with it, need all the help i can get?!?

Kross4031 · 02-01-2006, 06:37 PM

it's actually kinda simple. use the motor mounts from indian adventures. http://gallery.bcentral.com/GID47169...ebird-TA.aspx.

then use a jegster torque arm(cheap)http://www.jegs.com/webapp/wcs/store...egoryId=13055.

i used the stock 77 transmission mount. you'll have to make a plate to move the mount back about 2 1/2 inches. you'll need to get a custom driveshaft. cut the computer and harness out of the car. wiring it up is simple. you'll need electric sending units for oil/water. stock gauges work but are not very acurate with aftermarket senders. i used a griffin radiator from a 77 trans am and made custom mounting brackets.

hope this helps.

BigWerm05 · 02-02-2006, 01:59 AM

Thanks for the info, the car already has a carb so do i still need the computer stuff? Also what about the throttle, do I have to modify it at all, and do u know where i could find or how much a custom driveshaft is?

Kross4031 · 02-02-2006, 02:15 AM

you dont need the computer or any wiring associated with it.

this is what i did with my throttle . works fine.

DTS out of detroit did my steel shaft for 225$. they gaurentee it to 600h.p.

BigWerm05 · 02-04-2006, 11:14 PM

What kind of rear end is in the 84' Trans Am, I know its a 10 Bolt but is it a 7.5 or something else?

BigWerm05 · 02-04-2006, 11:24 PM

My Trans Am....Finally got some pics up...

Kross4031 · 02-05-2006, 12:34 AM

dunno. prolly gonna break it.

BigWerm05 · 02-05-2006, 03:02 PM

what did u do to your rear end and what did u do to strengthen it?

Kross4031 · 02-06-2006, 02:41 AM

so far nothing. i am waiting for it to break, then i'll spring for a 12 bolt or maybe a ford 9 inch.

its the 66-71, i belive "pontiac metallic blue" is the name.

and i wanted everyone to know, i just recently installed my tubular k-member from AJE racing, and now the indian adventure headers fit perfectly. on the drivers side, the only issue is one primary tube is really really close the the bolts that hold the clam shell to the k-member, and the pass side, i had to shave about 1/8 inch off of the oil filter adaptor.

and from the looks of things, i will have to take the number 8 primary tube off everytime i change my oil

but whatever, i feel its worth it.

Kross4031 · 02-07-2006, 01:11 PM

any chance of getting some pics of it ?

daturbosix · 02-08-2006, 12:54 AM

i dunno.. its got some sort of drain. batteries are dead after taking that one shot.

xpndbl3 · 02-08-2006, 01:35 AM

some nice guy hooked you up on that crossmember huh? also, doesn't tony or someone have a digi to borrow?

BigWerm05 · 02-08-2006, 01:48 PM

Which K-Member did you get, mounts/no mounts, Pinto Rack/No Pinto Rack? Im just interested because If I get the IA Headers i wanna know which K-Member will make them fit.

daturbosix · 02-08-2006, 04:46 PM

im pretty sure any tubular kmember would make the IA headers fit. but i have a AJE kmember with the factory chevy engine mounts for the frame side but bought the IA adaptor motor mounts for the engine side. i am retaining my factory front suspension and steering.

daturbosix, none of teh pics are coming up where I'm at, so I caint tell if you're runnign a remote oil filter or not. Just wondering about the oil filter issue w/the headers.

Kross4031 · 02-10-2006, 08:22 PM

i know when i fitted my i.a. headers on my engine outside of the car the primary tube hit the oil filter housing. i had to use a small oil filter. and by the looks of it in the car now. i would have to hire a really small contorsionist to remove that thing. a remote oil filter is definately the way i would have went if the headers fit for me.

eriesmoker · 03-01-2006, 07:21 PM

I am getting rid of my '71 charger and picking up an 82 trans am from my parents (mom don't drive stick) this weekend. It has a numbers matching 305 and 4spd. I plan on taking the 305 out and storing it. I've seen that a lot of people are having problems with header fit etc. I know that the 350 will swap easy, but my question is can I swap a 400 or 455 just as easily? And if I put in a 455 will I have to mod the suspension? A guy I know said dropping in a 455 or anything bigger than the 400 may require quite a bit of work. I am looking for advice on this. I've always went with the "stuff the biggest thing you can in it" mentality in the past....how does this pan out with a T/A?

eriesmoker · 03-01-2006, 07:22 PM

oops, anything bigger than the 350 (not the 400)

Kross4031 · 03-01-2006, 10:16 PM

the 455 i put into my iroc was only 65 pounds more than the 350 and all the crap attached to it. so modifications to the suspension .. only if it needed it before.

daturbosix · 05-16-2006, 03:54 AM

update...

car is back rolling. headers, tubular kmember, engine, trans, rear suspension.... everything done.

only needs some electrical work now.

where does everyone else stand with their cars?

BigWerm05 · 05-17-2006, 05:55 PM

I sadly ended up dropping the Pontiac 400 Swap. I optioned for the 383 Stroker.

As for an Update the 383 is complete(Edelbrock Performer 750 cfm carb, Performer RPM Air Gap Intake, Crane Powermax Roller Cam...558 Lift 248 Duration, Harland Sharp 1.6 Roller Rockers, Jegs Valve Springs...600 Max Lift, Eagle Forged Rotating Assembly, TCI Street Fighter 2500 Stall, B&M Street/Strip Shift Improver Kit, B&M Console Megashifter). I went with the 373 Gears. I beefed up the rear end a lil with an auburn posi and Moser Axles. The stroker took out the stock rear end, lol what do ya know.

I love this damn T/A, Runs 11.40's in the quarter!!!

I will get pics up asap!!!!
