Ok so i have a 1985 chevy c10 shortbed and id like to make it a street rod and mild strip truck (friday night after school only maybe saturday lol) and also sometimes a daily driver, when i can afford the gas... this is what i have to start off with
350 4 bolt main .040 over bare block.
th350 (needs rebuilt with shift kit)
the truck will be lowered but not slamed like lowriders or what ever you call them (cars). it will be lowered 2/4. and this is my question... is making 500hp too much for a street rod/ mild strip? and is making 500 hp with $5000 possible? If making 500hp for street rods is reasonable then how would i make 500hp?

Thanks for replying!

Check out this short block. It is a 4 bolt main block too. Chev 383ci Super Short Block, Early w/Driver Side Dip, 9.7:1-Competition Products. You purchase this short block and then purchase these aluminum heads Patriot, Freedom Series Alum. Chev SB Head, Assm., 190/64cc-Competition Products. This Howards Hydraulic Flat Tappet cam will give you the power you need. Howards, Hydraulic Flat Tappet Cam & Lifter Kit, Chev SB-Competition Products. Call about the short block and make a list of what does not come with it. Like oil pump, oil pan, head gaskets,water pump and gaskets, valve covers and gaskets. Go thru the list and see what you already have or can get cheap. If a block is all you have this is the way to go. This 383 ci motor won't be 500 horsepower but it will be fast. You really don't need 500 hp on the street. I forgot when it comes time get an Edelbrock Performer Rpm Intake and a Holley 3310 750cfm carburetor.

not having money for gas? build a 400 hp 350/383 a really good transmission and enjoy the truck

No 500hp is not too much. $5000 will get it done if you keep it simple
and spend the money where it will do the most good.

350+.040" Low 8:1 compression ratio (92 octane pump gas friendly w supercharger)
resized 5.7" GM rods reground cast GM cast 350 crank
low compression -22cc dished 350 pistons. (Speedpro-Probe Forged)
large chamber straight plug Profiler 195cc cylinder heads 70-72cc chamber. (K-2 spring package for mechanical flat tappet cams)
Weiand 177 Supercharger 2.10:1 to a 2.33:1 pulley drive ratio Holley 750-850cfm DP carb (boost referenced power valve modification)
Crane Cam F280-2 #114681
Scorpion 1.5 roller rockers
1-5/8" headers 2-1/2" dual exhaust.

Th350 with 10" 3500 stall 4.10 gears + sticky M/T ET streets. 10"x 28"
MSD Boost timing master. 28 -30deg timing under boost WOT

This simple Weiand 177 street blown SBC 350 will exceed 500 HP without even breaking a sweat.

I have forgotten to add this i already have an Edelbrock Performer Rpm Intake but my carb is just a Holly 660

Now i have a question about the supercharger... At first I was determined to get a supercharger but I did some research and people was saying that superchargers decrease the life of the engine... Is this true or not? Id still like a supercharger.

[vinniekq2]

are you sure the carb is a "660)"? Driving the crap out of your car/poor maintenance and cheap parts will shorten the life of the engine.

Im not 100% sure its a 660 but that is what i was told and so your saying a supercharger is fine as long as i maintane it and not put cheap little parts and gun it everywhere i go? i can do all 3... Thanks for helping and thanks for your time

No its not true.
The key to long engine life with a supercharger is to design the engine combo to be detonation free on 92 octane pump gas.
Thats what the low compression ratio is for and the Boost timing master is for.
The service life is not shortened.

ok thank you for that and sorry about all the questions... would my chevy 10 bolt 7.5 inch rear end with 4.10 gears hold the 500+ hp?

depends on its condition.
The OEM stock GM "cuckoo clock" posi is weak. A aftermarket Auburn or a Eaton posi for that rear is a lot lot stronger.
Proper ring and pinion gear set up is critical.
If the install/setup is wrong it won't last.
If the setup is right it will not be a problem.

The GM cuckoo clock "Gov Lok" G80 posi differential will not last 1 burnout. If thats what you got don't even think about it.
Replace it.

5 Grand??.Price it out with a parts list please.Current pricing and no magazine articles ref's please.

Blower maintenance??. Bearings/re-stripping the blower veins??.

The reason why the aftermarket offers forged crank snouts the increased size to BBC size on SBC cranks is blowers are hard on crank snouts and front main bearings.It is a way for them to address reliability issues that have occurred enough times for them to forge the cranks.

Gas mileage with a blower I doubt.They need a rich mix on both the bottom end and at the top end.Worst thing that can happen with a blower motor is a lean condition.

[F-BIRD'88]

The weiand 177 blower does not have strips. or need restriping.
With proper air cleaner and maintaining blower oil level this blower will go 75000+miles.
The motor does not need to be "rich" when not under boost. (cruising)
air fuel ratios are normal when the motor is cruising at part throttle at or near 14.7:1 is fine.
The overall fuel consumption will be the same as any other 550+ hp engine.
(if you can keep your foot out of it)
A forged crank is not nessessary. All GM rods are forged and are plenty strong. Nor is a dual key crank or BB snout nessessary with the 177 blower. the pistons are off the shelf speedpro forged.

This is not a 671-871 blower. Its not the same thing. These blowers are not hard on the crank.

This 350 blower motor is very simple and basic and can be built for $5000.
None of the parts are expensive or exotic.. All thats required is proper block crank /rods re- machining and assembly.
There is nothing scary or voodoo about a blower motor.
pretty much any 750 to 850 cfm DP carb is good and can be modifed and jetted for the blower for a few dollars.
You can build an better blower friendly carb than you can buy. Its not rocket science. a 950HP is ideal.
Even a edelbrock 750-800 carb will work very well. with rejetting
Any distributor can be recurved to work and integrated with the boost timing master spark retard box.
The fuel system is no different than any other 550-600hp capable fuel system It is not expensivie either unless you choose to make it so.
Two parallel carter P4594 pumps (7psi) plumbed thru two 3/8" fuel lines and two common 3/8" in line fuel filters, from tank to carb is all you need. You don't even need a pressure regulator.

When the time finally comes that the blower does need maintenance (after many many many miles of service) blower shops like Holley/Weiand, The blower shop, Dyers, etc all charge a set flat rate to rebuild this blower. Its dirt simple.
pretty much bearing and seals, gaskets, inspection, cleaning. Not much to these to go wrong.
and not expensive.

You do have to replace the blower belt once in a while. If the belt does break while you are driving, the blower just coasts/spins. you just don't get any boost. You still get home.

They key is to not spend money on glimmer and eye wash.

[F-BIRD'88]

You must use 92+ octane fuel and watch the total spark timing under Boost 28+/- deg with the 2.33 and 2.10 drive ratios.
The 1.95:1 drive pulley set will make OVER 500HP on this motor, on 92 octane (31-32deg timing).
If you build the motor differently you will get a different result.

[F-BIRD'88]

Your only problem will be keeping tread on the rear tires.
