funny you say that ....I stoped alot of guys going into the swap/show 2 weeks ago everyone I asked said Magna flow...thats the route Im going...

but the real question is how soon before the first burn outs??

Quackaddict · 05-05-2010, 09:48 PM

Is that cross pipe after the headers sold aftermarket or did you fab it?

Strut · 05-05-2010, 10:34 PM

I like magnaflow.... you dont get that metal clanging sound with the straight through design. Should have a deep tone to it....

'72customdeluxe · 05-05-2010, 10:37 PM

Magnaflows are pretty mellow (maybe not on that engine

) and get VERY loud under heavy throttle. No resonation with my magnapaks and no crossover.

I just finished my BBC502 swap and I went with Magnaflows instead of my Flowmasters that I had on the truck before the swap. So far I'm very pleased with them they're not nearly as loud at idle yet they still have a very nice deep tone to them. Once you get on the gas they come alive with a nice deep rumble, and there's not nearly as much drone in the cab. I'm not sure how much sound difference there will be between a 572 and a 502 but they're perfect for my 502.

Did you ever figure anything out on the upper radiator hose? If not I may have found a solution.

They sound pretty good at lower rpm but I'm not too crazy about the sound under heavy acceleration/high rpm. However, the performance increase is usually worth it. They flow significantly better than flowmasters. Your basic turbo muffler is like 50-60 cfm on 2.5" pipes, the flowmaster 40's are about 105 and the magnaflows are like 160

That H-pipe setup comes from Summit Racing. part number: SUM-642030
thats the 3 inch version.

Quackaddict · 05-06-2010, 06:57 PM

Awesome thanks that kit is aluminized wonder if they have it in stainless, none the less for 50 bucks I am gonna have to pick one up

handsomerob · 05-06-2010, 07:14 PM

well I hooked up the power steering lines, then I hooked up the brake lines to the master etc., I installed a summit swivel thermostat housing and flexible rad hose for now, and also slapped in a K&N 3 inch filter.

here are some pics

*highperf4x4* · 05-06-2010, 10:27 PM

Man that looks good!!!

How long till burnout video?

gixxerpymp · 05-06-2010, 10:36 PM

I want it.

handsomerob · 05-07-2010, 08:50 PM

Well did some work on the A/C system today.

Here is the old evap core

And here it is on the floor!

I found some surprises in there!

New Evap core installed

*highperf4x4* · 05-07-2010, 09:16 PM

Can you shoot me a close up of how that small copper tube from the expansion valve connected to the evap on your old one?

handsomerob · 05-07-2010, 09:30 PM

it had a thermal ensor on the end of it that was just clampped to the main tube commin from the evap core, 2 clamps thats it, this one has a copper winding @ the end instead of the thermal slug. I can probably get a better closeup tomorrow

*highperf4x4* · 05-07-2010, 09:41 PM

That would be aweseome I'd like to change my expansion valve and not sure how difficult it would be to mess with that line.

Awesome. Thanks!

handsomerob · 05-10-2010, 09:51 PM

Well got the truck ready today to be sent out to the body shop, Don't get excited, it's just having the frame straightened, we noticed the frame rails where a little tweaked on the back.

I just took a few pics, I'll be out of town for a few days so no work will be done this week.

thirdstreettito · 05-15-2010, 01:59 PM

BADPURPLE70CHEVY · 05-15-2010, 02:03 PM
