Thanks for your input guys. Blue Thunder it is. The manifold does not have a cut in the plenum divider,guess I will run an open 1/2" spacer under the carb. Cant wait to run the engine in the dyno and then in the car ! My friend has these TFS heads in his 482 ci -55 Tbird gasser and what a torque monster that car is. Anything over 3300 rpm launch and the car wants to flip over

Hi.
I am in the final stages of building a 428 / 462 stroker for my 1966 Fairlane GTA.I need to decide which intake to use as I have both.
Specs as follows:
Street / restored, Day 2 restomod style car. 428 C cratch service block 0.030 " over. Scat cast rotating assembly. Stress honed, balanced etc. 10,4 compression ratio. Out of the box TFS heads. Custom hydraulic roller cam with 236 / 240 @0.050 ( 300 / 300 gross) and around .600 lift.Custom made
1 3/4" full length headers with some tight bends to fit Fairlane chassis. 2 1/2" exhaust with h-pipe and see-thru mufflers..( also cut-outs fitted in case..you know..).
750 annular discharge Holley Ultra carburetor. K&N filter.
Engine redline / shift point 5700-6000 rpm.
Rollerized C6 with steeper 1 +2 gears from 4R70W. 2000-2400 stall ( against the brake)converter. 9" rear with 2,75 gears and TrueTrac, 31 spline axles.15" wheels.

The car will be used for overall cruising, and also highway driving ( 2,75 gears), with occasional quartermile runs with drag radials.

I have studied The Great Intake through many times during the years and also have tried both of those intakes in the car´s  previous 390 with around 450 horses. Both worked well, perhaps the ST Dom a bit better.

Now I cannot decide which one to use in the new 462.

BT intake´s ports match TFS ports perfectly. Street Dominator has a bit smaller ports and has been quite extensively ported in the plenum area.
BT would likely need an open spacer under the carb so that the 750 would not choke the air intake due it´s smallish size for 462 cubes.

I am looking for overall smooth rich brute torque curve with no hesitation below 2000 rpm but also want the powerful rush above 5000 rpm.

Thanks !

Thanks for everybody`s input, coming back to the original question about the grooves in the camshaft`s bearing journals 2 and 4... still do not quite understand why they are there, and why some cams do not have them ?

I am planning to have a custom mechanical flat tappet cam reground here locally, have a old core which does not have the grooves and was wondering whether they are really needed and should be ground in the journals.

This is a mild street motor ( 1963 topoiler stroked to 456ci already years ago), redline 5800,projected mechanical flat tappet cam to have approximately 238@0.050.

I also have some corresponding dyno data. 465" Engine with the EMC heads, and also out-of-the-box TFS heads.

Only disappointing part of the TFS heads is they hit a wall around 6200-6300

I'm wondering what you had going on there.  Maybe it was an issue with that particular pair of heads? 

Here's a 449 that I did with out of the box TFS heads:

Neither had a problem with rpm, so I'm wondering maybe if your heads had a port/valve job issue???

I do know that when I do a hydraulic roller with these, the setup has to be *light* in order to get them to pull on up.

Regardless, as you have shown, the amount of off-the-shelf performance that you get for $2600 is awesome.

Truly amazing figures for FE / strokers, both OEM iron and aftermarket aluminum. Have been used to seen these kind of hp/figures/ci for those 351 W / 460 strokers which I have been building for some 30 years -makes me really happy and looking forward to my new 462 build for my 66 GTA.

Mike, are willing to give some engine specs ie.compression, intake, headers ?

Hi.

Does a head with small intake ports ( appr 2" x 1.3" like C7-C8AE ), 2.02 intake valves and slightly better chamber, thinking of quench, than the basic D-shaped ( C6AE-R for example), exist ?`
Those C7 or C8 heads would fit the bill for me, but thought that if they had a chamber with a bit more quench,would be better.

Thanks !
