Gale Banks use to sell these nice cast iron SBC turbo manifolds with T4 mounting flanges and wastgate provisions but stopped production because "The foundry closed". His whole Chevy twin turbo kit was cool back in the day. Wish it was still available.
I came close to buying one of those in 1984. Instead I fabricated a twin turbo system (for about half the money). I still have a few turbo manifolds from various kits available back then.
I turbocharged my first engine (SBC) in 1976. Since then I've done a few other different engines over the years. The only way to go on the street (or a truck pulling a heavy trailer). In some cases I used kits. Others I completely fabricated the system. The dump truck in my avatar will be my next recipient of a turbo.
I appreciate your info. With your experience it would be cool to see you do some podcast interviews with guys like turbo john that are out in the racing world.
In the late 60s, Traco Engineering built a 10,000 rom SBC. Having grown up in Culver City occasionally a trip to the beach, I could see an engine on a test or dyno with its headers aglow.
I have an early 70s 388 Traco built SBC. It came from a vintage race team in Chino CA. It also came with a MacKAY magnesium 4 DCOE (I think) Weber downdraft manifold. I have no idea what RPM it was supposed to operate at, HaHa. It's a solid flat tappet cam.
I still think a 4-475hp 3500lb car is about right. It’s attainable, affordable and reliable. You don’t break alot of stuff and won’t get in terrible trouble.
I have a typical hot rod SBC 350, aluminum heads, weiand low dual plane intake, 2500 stall , comp XE268H cam, VSR7875 turbo, sniper throttle body efi, MSD6AL, only street use, it doesn’t run smooth under 3500rpm, but loves to party above 3500, what would be your preferred cam or intake for this set up -smooth highway and town cruising is the goal.
I have ran a 96 S10 with the 4.3 in it had to the head of and had higher compression spring just a little stiffer and was quick but not fast max out at 98 at redline
My '72 Nova came with a 307 originally. Bought it brand new and within 9 months I hopped it up with fuelie heads, an aftermarket cam and a Rochester fuel injection system. With a three on the tree and 3.07 axle ratio, it would eat stock (and some modified) big block muscle cars. Even then I knew turbocharging was the answer so in '74 I bought a new turbo and started my turbo journey with a 400 small block. Today, I have a 307 engine and when I look at the Nova (I still have it) I'm tempted to turbo the 307......just to see.
No engine on the planet will ever have the sales....into the billions...of a small block Chevy...I am a Cadillac guy...but Richard that's common sense....ford isn't even close what so ever!....
Hey Richard, I've got an 89 IROC-Z 5.7 TPI, it's pretty much all original so would have around 240 hp and 340 torque. It's fast enough for me! I think a mechanic might have taken my thermostat out, so I'm looking to have it replaced. Do you think I should order a 195 or 180 degree thermostat? I believe 195 is standard but I was thinking, having it running slightly cooler at 180 might help when I'm stuck in traffic during summer but I don't want to confuse the computer.
Why wouldn't they? This is the dumbest question anyone could ask. Turbo's are used as a crutch, to help a engine that's not built correctly. But when a N/A engine is built correctly, boost of any kind, only improves them better.
Biggest issue with SBC is the centre 2 exhaust valves and ports being Side by side. Creates extreme heat, Yes they will make power but I'd leave it at the drag strip only
@richardholdener1727 good point. I was seeing the question also as is it worth it say vs an LS. I have only turbocharged Big Blocks and Geo metros. Lol

a 268 cam in a 350 with a 2500 rpm stall should be good-check tune or step down to a 260 ish cam

How do I access these garage sale items you were talking about.
go to richardholdenerperformance.com (there is a garage sale section on the store now)
No engine on the planet will ever have the sales....into the billions...of a small block Chevy...I am a Cadillac guy...but Richard that's common sense....ford isn't even close what so ever!....
billions? just common sense
@richardholdener1727 Chevrolet alone sold 113 million....not counting the after market... Yes....in the billions of dollars....
This is live streaming. I thought it required action. ;). 😂
Will a Felpro 1094 .015 head gasket work with boost or should you deck the block and use a thicker head gasket?
you should not use a .015 gasket (you need more piston to head clearance-depending on deck height)

180 will be fine
@@richardholdener1727 OK great, thanks for the reply Richard!!
I’ll be happy with 600hp lol I just am getting a 1000hp turbo for that day i grow a bigger pair

@@stevethomas1301 This is why I've always been a BBC fan.
Agree. I have had a good combo engine just shine under boost.. not originally built as a turbo purpose.
If you have ever been in a classroom, you know the question isn't for the students who know the answer-it is to help those who don't
@richardholdener1727 good point. I was seeing the question also as is it worth it say vs an LS.
I have only turbocharged Big Blocks and Geo metros. Lol
