Big Block Drift Truck - Pic Heavy

[bba952]

Looks like you may have 1 or 2 exhaust valves receding.

they are good, its just there is a thick layer of cabon and it started pealing. had a hard time getting the head to separate from the block so i had to use a hammer.

The connecting rods have been stamped and are out if order so i know it has been rebuilt, im just surprised at the amount or carbon inside the motor.

deglazed the cylinders. there is still a small ridge on some but its good enough for this mild build

 

[bba952]

Did a test fit of all the major parts and double checked that i have all the correct bolts, and also the main cap studs came in today. They arent really needed but i plan on adding a small ebay turbo in the future.

must be getting twins.

Ha! i wish. I dont think this simple rebuild would be able go above 5000 rpm safely (nothing is balanced), so 2 turbos wouldnt be able to spool up fast enough

 

[bba952]

got the bottom end bolted in

twins will work fine to 5k. just need small ones.

My last two turbo vehicles have made allllll the boosts by 3k.. tiny turbos light right up. Assload of cylinder pressure making all that boost right at peak torque though.. same sort of power/boost curve on the 300 might stretch some head bolts.

he is bustin out studs on stuff....i just figured it as going up top too....

yea im going to get some head studs too. Trying to save money on reusing head or main cap bolts can turn out bad. $250 on studs is alot cheaper than a broken crank or hydrolocked motor.

on a 300? keeping 5k ish redline?


now....throw an atmosphere on there...for sure.

even with stock programming you might get away with the good injectors and pump and 10-12 pounds .

should bring it to 280 hp and probably exceed 450 ft lb.

geared tall....308 ish gears... it would drift well...

ran into a small problem when installing the new oil pump. the pump is a high flow stock pressure model from melling and its hitting the main cap studs. there is about 1/4 gap at the base of the oil pump and around 3/8 of the stud extending out of the nut. going to take the extra off the stud so it sits flush with the nut when torqued. the stock oil pump has the same clearance issue but a little smaller gap

Here is the stock Ford oil pump

your probably right but a like saying "ARP studs" lol

and im going to be using a blow through carburetor when i eventually turbo the motor. i know the tuning ability is quicker with efi but i like not have any computers on my vehicles

Considering how unique and kinda against the grain this build is..

You should definitely go with a draw through turbo arrangement. They always look so cool.

i can see this....but draw has waaaaaay too many issues with puddling and wheel erosion. the setups for blow through now are really good. i wont be surprised to see carbs becoming more common if people start catching on....i mean they will still probably incorprate computers with wheelie control and electronic ignition for crazy stuff....but for a manual trans brawler like this critter where a guy wants bare bones and minimal electrics, for damn sure get one of these blow thru carbs readily available....


between the turbo and plumbing/intercooler.... a good offy intake and ignition system you will be 3 k all in, but its gonna be a monster of epic kewlz nezz.


really, makes the big block look cheap....at this point. but this will be much more interesting for sure.

Blow Through Carburetor - Pro Systems Racing Carburetors

of course, i would just build a homemade bread box for now on top of the efi lower that will hold this blow thru carb and just run a turbo and no cooler through a carb hat or home made setup to get going.... hell, probably do that under 1600 with the new carb and it will be a beast. ignition might still be tricky but the speedway setup is pretty cheap.
