Intake Manifold Install on a Small Block Chevy with Vortec Heads

[@Rhawk03]

I’m putting vortec heads on right now! Thanks for the info!

[@lad63bird]

I Put silicone on every bolt so they all torque the same. Regardless of them invading into a water jacket you want consistency on torque spec and a siliconed bolt will act very differently than a dry bolt..

[@iowadiy6361]

That’s a good thought! I should probably use that technique as well!

[@darrellsomers5427]

If GM didn't use silicone you don't need too I didn't and I have no leaks ,if any thing it will screw with the true torque setting

[@Posibrian]

@@darrellsomers5427There are torque specs for wet or dry bolts. I suggest anaerobic Permatex in red.

[@mariomoscaritolo636]

use a loctite blue for sealing

[@lad63bird]

Also i never retorque bolts that are siliconed because you break the seal and can have leaks....

I just installed my Intake Manifold on my Vortec head 350 062 heads. What are the 2 - 3/16 holes in the Intake Manifold on your driver's side for ? (2:37 mark in your video) ? They go all the way into the Valley and I have no idea what they are for.

[@iowadiy6361]

I’m pretty sure that those are actually blind holes (not through to the valley) and are for mounting throttle linkage

[@graphic207]

hello I would like to replace the chevy van 3500 gasoline engine year 2000 with a diesel engine, can you refer me to a diesel engine model that can work on the van please.

[@johnnywrench5579]

A BLIND hole is closed at the end.

[@iowadiy6361]

Correct. I might have said that backwards

[@dewaynebanks5369]

Which intake fits a 2000 s10 4.3 vortec

[@riccjames6514]

Wut the part # for that intake Manifold from summit

[@iowadiy6361]

It’s SUM-226018

[@wildwillscustomsexhaustvid9677]

What bolts did you use. Also are the ports for heater core hoses?

[@iowadiy6361]

I used an intake bolt kit from the auto parts store. The ports could be used for heater core hoses or also could be for bypass lines (only needed for racing or extreme temps)

[@wildwillscustomsexhaustvid9677]

Awesome thanks

[@Vanchero1955]

How's this engine holding up?

[@iowadiy6361]

So far so good!

[@Tacuache602]

Do you have a part number for the gaskets

[@iowadiy6361]

I believe I used fel-pro gaskets. The PN for Summit Racing is FEL-1255

[@Snailmailtrucker]

Nice job Liked/Subscribed

[@adancortes3568]

do these intake manifolds fit on 97 5.7 vortec ?

[@iowadiy6361]

Yes it is designed to work with vortec heads

[@bobsilver3983]

Only 15 foot pounds?

[@iowadiy6361]

It sounds low, but that’s the spec for it

[@buckwall8410]

Felpro has a metal core that one doesn't

[@iowadiy6361]

Good to know! I'll keep that in mind for future use
