[@ScottsFormula350TPI]

Every one of these vids has given me lessons on restoring our raceway to the roadway Formula 350.. Thank you soooooo much sir for sharing your knowledge with us.

[@VetteSource]

No problem, Scott. Glad to do it👍.

[@vyres706]

Great vid thanks for the help. Rebuilding my 350tpi for my 89 camaro!!

[@VetteSource]

Glad it was helpful👍. Sounds like it will be a great combination when your finished.

[@wadecreighton4584]

These are invaluable to a tinkerer like myself thank you very much

[@VetteSource]

Awesome! Glad to hear you enjoyed it. I should have the third part to this video up shortly.

[@annpatton7796]

i purchased a 85 corvette that i am going to replace injectors with bosch and the fuel pressure reg with an adjustable one, i have been watching your videos this evening and it is so helpful and less confusing. thanks

[@VetteSource]

Great! Glad to hear that the videos have been helpful. The Bosch injectors and adjustable regulator is a good combo.👍

I have a 1986 iroc z with the 305. I'm putting new intake gaskets and new harmonic balancer thanks for the videos because I forgot where my vaccuum lines go back to, and some hoses lol

[@VetteSource]

No problem man, glad they helped you out with your gasket replacement.👍

[@milesmania1150]

Nice job show how to get down to the intake base

[@VetteSource]

Thanks, keep an eye out next week as I start to put it back together.

[@DJ80s]

How do you get to the bolts on the bottom??? It's a very tight squeeze and a terrible angle. I wish that would have made it into the video instead of just filming them already loose. I'm trying to get my plenum on right now with new gaskets and it won't go back on so I need to loosen a runner but the bolts are obstructed. How do you fit the bit on the bolt and loosen them in that compressed space?

[@VetteSource]

Yea, the bottom bolts aren't very accessible. It helps if you take off the valve covers, and use a swivel adapter to get some upwards angle on your ratchet. Just remember to not overtorque, the torx heads will strip easily.

[@JuanDopes]

Can you make a video showing how to replace the whole egr temp switch assembly on l98 corvette?

[@VetteSource]

Are you looking to replace just the switch, or the entire EGR crossover pipe from the intake to exhaust manifold?

[@JuanDopes]

@@VetteSource forums are recommending an egr delete instead but i can't find any videos on that do you have one?

[@XXavierSin-XXs]

My trans am has this motor; I'm trying to replace the injectors but getting the runners off have been such a pain.

[@VetteSource]

Yep, they can definitely be frustrating especially the two hidden bolts at the lower mount points that come in from the opposite direction.

[@XXavierSin-XXs]

@@VetteSource Yes! I've seen someone use a special tool but I cant find it anywhere!

[@VetteSource]

I seem to remember that tool, but it's been a long time since I've seen one. You can also accomplish it with the right mixture of universal sockets and extensions.

[@jacobdeleon8947]

Can you tell me what alternater you have I recently bought a el Camino with that engine but It needs and alternator but I can’t find one

[@VetteSource]

I purchased an AC Delco Part # 335-1012 off Amazon Warehouse deals. Looking at it I see they still have them in stock

[@samh4333]

I have a small block 350 with TPI system. It’s currently in a 71 Elcamino. Can I use another aftermarket system like FiTech with that manifold?

[@VetteSource]

Hey Sam, I'm not sure how you would integrate the computer controls from the aftermarket system with the TPI due to how simplistic the processing speed of the TPI is. Also, the unique design of the intake runners and manifold may not match up very well with the programming of the aftermarket system.

[@samh4333]

@@VetteSource Thanks for the response. I’ve decided to go back to a carburetor.

[@samobregon4699]

Thank you for this video helps out but I have some issue with my with my unit it overfill the the pistol walls or the Pistons it seem like it's filling up fuel very quickly and it just overfill everything up walnuts tiling for a few minutes it overflows my cylinder walls if you haven't answered let me

[@VetteSource]

Thanks for the question. My first thought would be you have some bad injectors. The coils inside have failed and they're not holding the fuel back like they should with the engine turned off. It sounds like you have already verified what is actually happening, now its just time to replace the injector set.

[@samobregon4699]

Thank you very much for replying back I have replaced the fuel injectors on that vehicle but it's something wallet Island all the sun just fills them up I think there's more issues behind that is there a way that I can contact you or or send you a video or in the future what's going on

[@VetteSource]

Sure, you can send a video or message through DM @VetteSource on FB or IG. You will also find my phone contact information there as well.

[@samobregon4699]

@VetteSource thank you . I'll will . Thank you for your help

[@jbhobbyist9372]

What is the tork spec/ ft. lbs. for the upper intake runners bolts?

[@VetteSource]

They have a range from 25-45 ft lbs. I would shoot for around 30-35 personally. Thanks for watching👍

[@michaelcarroll9930]

Your knowledge is awesome but your camera work needs room for improvement

[@VetteSource]

Thanks Michael, appreciate the feedback. Going to be looking into a few tweaks to see if I can get some better camera stability.

[@dukeman7595]

@@VetteSource That will be great because you have the best how to content on KZbin, especially with corvettes.. The people I shared your videos with loved them, but complained about the camera movement. I think your channel would have grown more if the videos were stable. Just advice from an avid subscriber. Thank you for your work..
