Honestly I love this. 1. A non-standard engine with parts someone could find. 2. Some NA and boost dyno results to show before and after. I wonder what 10psi would have looked like? Would it still be driveable? Please do more odd style engines, its fun to see how NA to boost affects them.
It doesn't have to work perfect, it just has to work! Stock cam and boost are always great for mid-range power...and in most cases makes more than a typical hot NA setup.
Those poncho 350's have always been kind of underrated. I've seen them run just as rowdy as a 400 with just mostly a head and cam swap. I had a 350 69' firebird I eventually did a 400 swap. After all the time and money, I couldn't really tell much difference. I now have a cheap 326 I paid $150 for. I've thought about building it for boost. Maybe try to fab up or modify a intake set up like that came on the turbo T/A 301's. But probably easier and safer to just go with aftermarket fuel injection. Just a set of modern aluminum heads and a nice roller cam setup. That lil 326 would outrun my Ram 3 400 But the best part If I blew it up I'm not really out much vs imploding one of my 400's or my 428. The prices people are asking for even the mid/late 70's low compression 400's over the last few years is almost as ridiculous as the recent inflated prices at Mcdonald's.
This is the stuff we all watch your channel for! Taking old junk and making power! Now you have to try a 301 or find an Oldsmobile paper weight 260ci v8 with a turbo.
I love these Pontiacs and rebuilt several as my first engine projects. The 350, 400 and 455 are all the same engine. Almost identical except bore X stroke so those extra heads will fit any of the 3. 2.11 and 1.77 good sized valves on the 6x’s if memory serves from 30 years ago. Lower rpm range than a Chevy but lots of power for its era. Excellent video!
Awesome! Thanks for representing the other-other guys! 350 Pontiacs don't get much respect even among Pontiac guys. I'd love to see a dedicated other guys episode with this engine and see how much boost it'll take! 🙏
@atenooie I almost need a different engine for each type of driving I'm going to do. Sometimes I want a 5 liter, a 5.7 and some kinds of driving requires the full Monte . . . 455. So many choices, hard to settle on just one.
I’d love to see a video exploring the merits of engine coatings. Ports, chambers, piston crowns, headers, bearings, etc. just to see if any coatings makes financial sense when searching for power.
You made my gto setup. I tagged you on Instagram too😂😂😂 I have a 1972 350 with a 7875 and holley terminator stealth blow through. I have a few short clips on youtube as well. ❤
Thanks Richard, you inspired me years ago starting with the GT45 on old engines. I made my own kit on a 350 Oldsmobile with no.8 heads, 1976 Smog motor and that GT45 turbo. Put a FiTech 600hp Power Adder on top and a locked out HEI. Put it in an old Altered Chassis and now runs mid 10’s with 8psi of boost on a non prep track, Cheap fun!!! ruclips.net/video/9SPM8tbzEF8/видео.html @14:55 Sorry that it is in German 🙏
@@richardholdener1727 Thanks for taking the time to reply 🙏🙏🙏. Currently the rear end gearing is not long enough. I will put in a 3.73 instead of the 3.91 as it hits the limiter of 5800rpm @126mph.

@@maxpower479 I start on the 2-step at about 2500 rpm with 2,5psi.

Return of the turbo drain in the old fuel pump location so I did not have to drill the oil pan.
This is crazy but here goes, how about a shoot out of NA 6.1 hemi, 6.2 ls, and 6.2 SOHC Ford? Too crazy? How about a series on the 6.2 Ford? You’re the right guy for the job.
Ah Richard can you make a video about the Crossfire V8 in the 84 Corvette mods to help the factory 205 HP to something a like bit more thrilling. Thanks love the channel.
I'm such a ding-bat sometimes! I The entire 11 minutes is just watched this I couldn't figure out how it was running without the fuel pump connected to any lines. Lol Seeing that sludge brought back memories. Get a junkyard motor. The pans would always have a inch thick of mud. Think oil is a lil better quality in the last 20yrs
Love your videos! Thinking of doing this to my ford 360FE ratrod. Did you use any electronically controlled systems like an MSD 6al-2 for timing? Or did you set timing and go with it? My goal is 7psi of boost, blow thru carb style
With the weak wearing on the crank shaft the black would have very little strength to hold back the rotating mass underboost extreme boost I mean added protection are you going to do for the block I've seen the crankshaft and connecting rods and pistons eject themselves out of the engine going down the quarter-mile
I wonder if it's possible that the increase in power provided by headers is due to the pistons having less pressure on the exhaust stroke, freeing up power to the crank.
Get a 750 holley dp, replace the brass floats, get the weakest power valves you can find, drill out the powervalve bypass holes a couple bits, jet up 5 sizes (or so), make sure you've got a fuel pump/regulator that can supply 1:1 fuel/boost ratio, those are the basics, there are a lot of other things you're gonna wanna do, like vent extensions and whatnot. bottom line, is you need a wideband to tune with or you'll be making aluminum crumbles quickly.
Richard, does the distance from the exhaust ports to the turbine inlet actually have a lot to do with turbo lag? I'm really considering a turbo in the bed of my truck vs under the hood is why I'm asking. I keep recalling proper turbo sizing is key in all your turbo videos, and not much about placement.
I don’t know about lag but I got halfway thru a rear mount turbo project and ended up moving it to the engine bay. There’s more room in the bed, but running the exhaust and intake tubes all the way to the front is a huge pain. Lots of leaks and trying to rout stuff around frame rails. Unless your putting a 454 in a mini truck you’re better off just making some room in the engine bay (or cutting a hole in the hood!)
Where do you put the oil and coolant lines into the motor. I'm also boosting my 77c10 and I have all I need just can't figure out where I should put my lines
Man. That setup would probably rip on my smogger headed 400sbc with a decent erson cam in it. Hell it woyld rip on my 4.5 ltr Mercedes v8. Do you think a gt 35 would be better on smaller displacement not going for more than 400 ish? Its probably 200, so maybe 240-250 on the Dyno setup.
Be very responsive 35r is what early model Barras had factory. Mine was very mild , valve springs and 12 psi boost. Full boost by 2-2200 rpm on a 4l 6 and 420 atw hp.
@@richardholdener1727 Hi, I'm French and don't understand your language perfectly, and it was by watching the video the second time that I understood that it was low compression because that power wasn't ridiculous in N/A.👍🏻🐯

can be done with stock manifolds too
