The plan: Keeping it mostly stock for now, to get everything fabbed up (motor mounts, tranny mount, driveshaft, shift linkage, etc) then ill start modding it after its broken in.

The only mods now is, edelbrock 650 cfm carb, performer intake, msd cap/rotor, accel points delete, msd ignition, and it already was bored .040 over along with headers i find to fit in the supra

Finally found a doner for my supra, a 350 and a th350 tranny. Picked up a '78 Chevy Pickup for $300 It has a Dana 44 front axle, a dana 60 12 bolt rear, and a np203 transfer case that im selling to make the money back and rebuild the motor.

Sweet header, only one

Missing a carb and a starter

Truck in all its awesomeness........

Obviously sat for awhile, need to clean up the heads.

Cleaned up one piston

More crap

All clean and cylinder walls are good

.040 over which makes it a 357ci

More progress today, put the engine on my stand, pulled the other head and pulled the pan and water pump.

This side looks way better then the other side

There arent and rustcicles on this head

Drained the pan, yummy milk from it sitting

4 bolt mains was a surprise, from what ive read trucks didnt have 4 bolt mains so must be from another car

some updates

honed the block
cleaned all of the pistons, rings, bearings, tappets, and caps

need to clean the block, crank, and cam

will post pics of the block tomorrow with daytime light

rod bearings were replaced with clevites they all have very unusual wear, most are offset corners so top left, bottom right whats that mean?

an example of all the other bearings

clean pistons

cleaning and lubing tappets

main caps, the one cap has .010 off of it, but the thrust washer looks fine. there is alot of crank play

goodies double timing chain, with option of retard and advanced cam timing. and chrome stuff i picked up for cheap. all for $60 at my friends checker store

 

[stevenr816]

got a new water pump, lifetime warranty along with paint to start painting. decided on straight red engine paint

 

[stevenr816]

cleaned up the block and painting it. also picked up a starter, only use to honda and yota starters, this things a beast. putting the bottom end back together tomorrow.

 

[stevenr816]

Me and albert have spent alot of time sand blasting things. And spent Christmas eve together...... sorry Carlos.

Picked up some goodies, edelbrock 600cfm carb and "permormer" intake for $100. The intakes performance is definately in the weight alone compared to the cast pos.
Also got and alternator relocation kit, made it down low instead of on top definately looks better, along with adjustable linkage brackets from lopers.
Ordered a oil cooler housing on eBay mated up with the cooler I picked up from Jason.

If any places were open it would be done, I just need to lap the valves but no one is open to get lapping compound till Saturday
need to paint one more head.

teaser

heres some videos

first one starting, timings not set, vacuum lines off, centrifugal advance sticking open and cyl 5 not firing.



now, everything fixed. timing at 6* advance, valves adjusted, vacuum lines hooked up, sticking advance fixed, have to fun the crappy valve covers to flip the headers up since they wont fit down with the engine cradle.

 

[stevenr816]

need to get headers like this, something from a newer chevy pickup ive been told.
the headers on the engine now are just to start it.

and then as far as the rest of the exhaust back, i havent decided yet. i have to choices
1. having dual 3in exhaust all the way back coming out the rear bumper
2. coming back,and then exiting in front of the rear tire

drag car,

being bored and wanted to do something new since mostly everyone is doing JZ's now these days. plus it was a good deal for the motor and seemed challenging since i've only seen probably 2-3 350 swaps, and only liked one of them the others were a complete nightmare.

plus i love super clean engine bays like how my 1j was

 

[dubsupra209]

yea that is a beautiful engine bay....why didnt you go 302..? or are you a chevy man...?

i'm hoping for atleast 13's on street tires as long as it hooks, seems reasonable since the car is completely gutted sound deadening too, bucket seat, and has suspension and bushings.

In the long run 10s after ive built the motor up. i would love a single digit pass that would be sick.

but i have no clue. 350's had anywhere from 175hp-almost 400hp stock. the motor that came out of the pickup wasnt the original motor so i have no clue what heads, cam, intake, or carb was on it to know which motor it actually came out of.

i have 2 out of 4 solved since i put an edelbrock intake and carb on.

second, im sure the torque convert is stock but you never know. its super clean so theres always the possibility its i higher stall, same with the tranny whats done to it.

:squirt-modude i love the car its awesome and i am a chevy guy so i love it even more

Nice build you have here. More and more people seem to be talking V8s in Supras. It is about time. I bet your engine weighs no more than a 7M with turbo/intercooler setup.

 

[dubsupra209]

i think you would be defienlty capable of 13s when you do go to the track make sure you have footage of your runs id like to see them.... :biglaugh:
