Good Evening,

       Has anybody ever used a Blue Thunder intake manifold with there 292 engine?  If so are you happy with it?

Thanks,

Ray

Well, what do you mean by 292? Stock or modified? I use one and am happy but the engine is quite modified.

Ray's post brings up a related question that I've asked before here.. and never got a straight answer. Are Y-Block Blue Thunder intakes still being made?!.. I only know one person personally that is using one, but it's not on a 292, it's on a slightly modified 312 with headers. He's happy with it. However, my impression based on one or two earlier Dyno tests, is that on a stock or near stock 292, performance below say 3000 or 3500 RPM will likely be weaker than with a 4 Bbl "B" intake.

Ive been running a BT on my 292 for about 10 years....ive got a bigger cam and a fom. It breathes well at upper rpms (which i rarely get to thanks to the fom) but lacks low end torque. Would be much better suited for a stick car, imho.

Blue Thunder intakes are still available.  On a dead stock smaller cubic inch engine, the stock iron ECZ-B intake will have stronger low-end torque numbers but if you’re after passing gear performance or do a lot of spirited driving, then the BT intake will still shine in the upper rpm band.  If you have the hood clearance, then using a 2” four hole carb spacer on the BT intake can restore some of that lost low-end grunt.  Ford had the ECZ-B intake matched very well to the stock G heads with stock 1957 camshaft so that’s a tough combination to beat on something you simply drive every day.  If the heads are ported, cam upgraded, and the exhaust system improved, then the BT intake becomes a prerequisite.

I have two of them, one for the dragster and one for the Uni. Charlie Burns also used one on the "Brick's" 258ci engine. All were high reving engines and the BT works very well. The Uni now runs a Mummert intake and the dragster goes back and forth between the BT and a 573 Edelbrock.

This info may not mean much to the "street" guys but I will add that I've been very happy with just the stock "B" intake on my '58 pickup.

When I bought my wagon it had a Blue Thunder in it. I don't have anything to compare it to, but I'm pleased with it. As far as I know, it is a totally stock engine with Edelbrock carb, Blue Thunder, Pertronix, stock exhaust manifolds and dual exhaust. Works great for my daily driving, mostly highway miles.
