Some progress pictures 70 K5

[Jason915]

Went 4wheeling on Sunday and my fuel pump failed so didn't get any action pictures my brother in law had to tow me to town so I took some pictures at his house when we got back. Bad day for 4wheeling

Before







After





I bought this in Janurary for $500.00 and have been working hard to enjoy it this summer. As you can see I still have a lot to do but it's comming along nicely. Next disc front brakes and 3.73's

Whoa, had me scared when I saw the first pic, had no idea of what to say when I saw it.

Then I saw the rest... now I do! Great transformation!

Looks like a totally different blazer, your hard work has paid off.

LOL scared you that's great! Thanks I have been working on this missing out on camping dirt bike ridding and fishing all summer so now that it's this far maybe I can still enjoy it before there is snow on the ground. I am really mad that the fuel pump went out because it's brand new Holley TBI pump and it has a filter before and after it. It was a pain in the butt getting it back to town today.

overall I am happy with the TBI, the thing I like best is that it don't flood out on steep hills and no gas sloshing around in a carb off road. I think that I need a larger throttle body though I think that the stock TB and intake are a bottle neck becasue power is decent but not anything to brag about. .060 bored 350 with 285-300HP marine cylinder heads comp cam and headders and a custom chip it feels like a peak of 220ish HP and 285-300ish peak torque to me. I built the engine for 250-270 HP and 350+ torque but it don't run that hard. Also my transmission is a slush box not very responsive and with 3.07 gears and 33" tires excelleration is lame to me. When it winds out it pulls nicely so I know that there is potential I just need more low end power to get the truck moving. That is why I say next modifications are 3.73 gears, the only reason I am not going with 4.10's is becasue I have a front axle D44 with disc brakes and 3.73s readdy to go and a 12bolt with 3.73's just ready to put in.

Thanks for the complements guys, It totally looks like a different truck and I get a lot of complements while I am driving it.

May not seem like much but 3:73's are a much friendlier all around gear than 4:11's for a driver.

Wish you were closer, I'm sorta looking for some 3:08's.

[Jason915]

3.07's are terrible up here in this nose bleed altitude and mountains, but a great sea level gear. I just drove my GMC that has been sitting while I have been driving the Blazer and gezz what a difference 4 speed, and 4.10's and a 300 HP 350 it feels like a big block compared to my K5 lol.

Great transformation!

[Jason915]

Thanks Yukon, I am just mad that it's already broken down. The fuel pump is still on warrantee so I can get a free replacement but the down time sucks and now I am paranoid that a replacement will not last. I cannot stand to be worried about something like that.

[Jason915]

Update, fuel ump is fine just a wire to ground easy fix runs again. Sat morning I am going to try a 4.10 out back to see if I like if so then I'll put them in the front!

1) Usually the throttle cable goes to the top stud. The long black one was for cruise on the R/V series.

2) Assuming a frame mounted tank....you can use a 31 gallon 87-91 tank. Get with mosesburb here or on ck5. He used the tank that used to be in my 79 K5 years back when i made the tb swap. I don't generally recommend holley as it is easier to find a replacement part if it was a factory item....that why i use a tb tank and factory pump set up....plus its in the fuel vs. having to pull the fuel from the tank.

3) howell or painless harness? Guessing at a howell as painless doesn't wire loom their stuff. Running a vss (2 pulse) ? If not leave the black wire for the park-neutral connected. If the cam is way off in lift and duration you'll have issues...if the block is from the old days and you are running a non tb cam you will have to advance the timing into the 12-14 range to make her happy.

4) Pull the injector pod off (2 lines and 3 torx head screws 3 fittings) put the staked nut in a vise and turn her 3 turns counter clock wise to raise the psi up a bit...

This ought to wake her up a bit if i am guessing right....

thanks 1975k5chalet, my throttle is a linkage type and it worked out best using the cruse mounting spot.

It's a painless harness I put the loom on it. Running a VSS, and a park neutral kit from painless for a park netural signal to the ECM. CompCam cpu friendly and a custom chip from TBIchips.com. I'll try bumping my FP up to see if that'll help. I put a 4.10 in the rear this morning and that helped a lot.
