BBC Headers for 4 speed

[fmstruck]

I am putting a 427 in a 1984 K5 with an SM465 with hyd clutch. Can anyone give me a link or part number to a cheap header that they know will work. Everyone lists either 4wd auto or 2wd manual, but finding both is not proving to be very easy. Any help would be appreciated.

I got some manifolds.

Sanderson Headers offers some shortys that will work but they're not cheap.

Try looking at Flowtechs, they are cheap price(think mine were $130-$140). Work fine on my 81 454 K30 4 speed. Thick flange, good size tubes and seem to be holding up ok. Close to the starter though, I put a heat shield on it and have had no problems.

bbc and headers

I used Hedman mid/shorty header. They're coated and about 300.00 and are 14 gauge with THICK flanges. Excellent quality!!! They have the same header available without the coating for about 150.00....New. Part # HED68618 for the coated headers. Hope that helps'ya...

I don't remember what brand he used, but he had to dimple the pipe for clearance at the master cylinder.

I used hedman longtube headers. Were meant for an 84 chevy k20 pickup truck with a 4x4 auto trans. Fit perfectly.

Yes, but did you have a Hydraulic clutch, or a mechanical clutch linkage?

[us74k5]

Mine is a mech clutch. However it looks to me like they would fit with a hydro clutch as well.

 

[tsr1972]

Mine is mechanical linkage as well and they were a near perfect fit. Fit a whole lot better than any long tubes and the construction quality is ALOT better than others.

of course they fit better.. it's a shorty, it should.. long tubes have a substantial performance edge over a shorty... might as well leave it manifolds at that point imo...

I have Doug Thorley Tri-Ys and they are awesome... Fit perfectly. I had to take the bumpstop that contacts the pinion flange on the 10B off but other than that they were PERFECT...They were not cheap though...

Part # THY-304Y

I think I paid like $400 like 6 years ago for em

hows the coating held up?

 

[fortcollinsram]

hows the coating held up?

Very well actually...It has dulled in a few spots but no rust other than on the header bolts

 

[ryoken]

ceramics?

i always liked the tri-y.. a cross between a shorty and long tube, good ground clearance and fitment of a shorty, while maintaining the performance of a long tube.. debatably, of course..

I need to make a choice, soon... Thorley's a top 3 candidate for me.. but I really wanna go stainless if i can......

I used hedman long tubes on a 78 with a 454 4 speed, they fit good.

Once again, with a hydraulic, or mechanical linkage?

I have a set of hedman long tubes on my K5 temporarily to break in the motor - 454 / OE hydraulic 4spd parts.

Once the motor is running and broke in I'll be installing my Sanderson shorties.
