Build up thread of my "SS10 Blazer"

Lots of different cams to be had.  Pick your fav'!

I can't say for sure exactly which is/isn't a roller setup.  Seems the later the year, the more likely though.  Mine's a '90, but out of a cop car (L05).  Here's a link to ThirdGen.org where a guy shows ALL you'll ever need to know about building up a 350TBI engine.  I read it about 20X.  Then of course only did half of it.  ;)

A stock 350TBI in your case will probably be fine since you're shooting for more low/mid range power.  With very minor tweaking you'll get about 500cfm so that's plenty for lower end RPM.

I went with the Edelbrock mostly on price, but also on versatility.  It's actually a 4bbl meant for Vortec heads, then I added a TBI to 4bbl adapter plate.  I've got to make a new one though, to clear the huge 2" butterflys of the 7.4L TBI (it hits the sides of the intake).

Hmmm...   me thinks I forgot to post a follow up (from, ya know, 5 months ago!!).

Hood got roughed into shape, installed, then promptly ignored. 

Went through the summer with no overheat issues (save the the time my e-fan decided to no longer turn on under ECM control) even with the stock 4.3L rad in it.  As a matter of fact, I'm going to change the T-stat out since it's heating up too SLOWLY!  I drilled a couple of holes in it to prevent air traps...  and I think I made them too big.  Oops.


Did a few other things over the last 6 month, but nothing major.  Made up the console gauge panel that a few of you have seen installed

 - but I'm going to pull it out and re-do it since the angle is too steep (near flat!) and I can't see the gauges clearly unless I lean forward and look down on them. 

Added a phenolic spacer under the throttle body adapter to reduce the temps of the TBI unit from so hot I couldn't touch it (really!) down to it feeling like it's a refrigerator unit!  It's bizarre.  It's actually almost ice cold!  Guess rushing air and the cooling effect of the fuel does that.

Anyhow, that's about all I can think of....
