Choosing the correct camshaft profile is critically important.
The lower the @ .500 lift intake duration the more torque the engine will make under 4000RPM.
Increasing duration will raise the peak horsepower number as peak torque is elevated in the RPM scale.
I will help you select the ideal camshft
I do a turnkey 383 engine for $6500.
You can have it with 9.5:1 CR for low octane fuel and a short duration cam for max torque at low RPM, or a 500Hp combination, same price.
I am able to offer this engine a veriations of it because Imade an aggreement with a very large engine building company you may have found on the web because their pricing is amoung the lowest in the world.
Rather than compete I just have them supply parts and engines to me.
If you are looking at engines at lower prices than theirs you are looking at lower quality.
Over there years most engine builders have learn what low price parts to avoid.
Got questions, just ask.
King SI-Series main bearings are recommended for OE applications. These replacement bearings are designed for aftermarket gasoline or diesel engine rebuilding—and performance engines with factory crankshafts. The bearings have an improved crankshaft finish for reducing microscopic ferrite peaks on improperly ground or polished nodular cast iron crankshafts. King SI-Series main bearings feature improved oil clearance to reduce wear and increase engine life, which in turn reduces operating noise, vibration, and excess oil flow. Order the set designed for fitment on your make and model.
Chevrolet Performance LS3 hydraulic roller lifters are designed as direct replacements for your engine. These lifters were designed for use by GM to be used in performance engine builds and incorporate improved valving to allow higher rpm capability.
The exchange rate between the US dollar and most currency dramatically raises the cost of building a V8 engine.
$10,000 spend in America can quickly turn into $15,000 local dollars or 9000 Euro.
An engine's cost is the sum of the parts used and the labor involved.
Working with my supplies I've compiled a list of parts beginning with the lowest cost and moving up to the more expensive stuff.
I can supply just individual parts for the "do it yourself builder" to a complete turnkey engine.
To give you some idea of cost I have written the following
When you need the best, you go to a specialist—and for the best bearings, you see King Engine Bearings. King focuses on one product—bearings—and nothing else. Their innovative, race-only Xtreme Performance tri-lecular main bearings are proven track-tough to handle the ground-shaking power of your race engine. Built with enhanced tri-metal, these XP-Series main bearings layer copper lead construction with a nickel plate barrier and a lead/tin/copper babbit overlay over a steel backing in an adhesion process that provides superior stability and durability. King's advanced control measures hit a bull's-eye, maintaining wall thickness tolerances far tighter than their competitors—an amazing +/- .0001 in.! These XP-Series main bearings are narrowed for large radii crankshafts and feature enlarged, chamfered oil holes with full, 3/4, or 1/2 grooving for improved oiling. How many reasons do you need to use a specialist? King XP-Series main bearings deliver consistent and reliable performance with a high-load capacity, and the prognosis from the specialists is a long and happy life for your engine.
King HP-Series main bearings are recommended for street and strip performance applications. They're designed for blown, turbocharged, NOS, and alcohol-fueled engines using aftermarket crankshafts. These main bearings have greater eccentricity for superior oiling at high rpm, and a chamfered surface for large radii crankshafts. HP-Series bearings also feature large, chamfered oil holes—and are available in 1/2 grooving for improved oiling to withstand high-rpm applications. Order the bearings designed for fitment with your specific engine.
For similar information on Fords or big block write to me below.
If you want the most power you need the most CID, 434.
With a low RPM combination, 560Tq is on the table, for street strip racing well over 600Hp.
Expect to spend $10,000
• Cold forged steel body heat-treated for exceptional wear resistance.
• Precision ground needle roller bearing with high chromium steel axle for long life and minimal friction.
• Cold forged extra-long piston, precision ground and fitted for controlled leak down and pump up.
• High flow disc-style quick reacting check valve for better reaction at higher RPM.
• Precision oil metering assuring proper oiling to the rocker arms without sacrificing oil pressure.
• Proprietary tie-bar system
• All hydraulic lifters are available with short travel, variable duration lift, and axle oiling features.
Based on what I wrote about the 46500 SBC I can supply a BBC 572 for $11,000 or a 496 2 bolt main for $9500
Supercharging.
I can build you an engine with a GMC style blower, a Procharger or the cheaper Torqstorm.
Turbocharging is the best power adder for the street but a more complicated build.
If you calculate for the lowest cost stroker kit you will come to approximately $1000.
If you want a forged crank and piston kit plan on at least $2000
Contact me and I'll help you choose the best parts for your combination
Cylinder Heads.
For lower RPM engines say for a light truck stock heads will do the job.
Stepping up to a 383 CID makes the additional torque you are wanting.
However, reconditioning used iron heads might cost $500.
For $600 you can have better Asian aluminum heads,
There are brands to avoid, I provide those brands I have confidance in.
The cheapest decent heads are Flotek. $800
ProMaxx 200cc are very good, as are NBK 200cc.
The castings are good quality and the flow numbers can make 500Hp.
For low RPM Tq I use small intake runner heads.
The best for the street and most racing are AFR
You will need head gaskets, and blots to build a long block.
If you want the oil pan, timing cover, intake manifold and valve covers, I do a $5500 combination.
Step it up to a turnkey with an alternator on board $6500.
If you find a lower price combination, then you can figure they are using cheaper parts.
A well-known supplier of Chinese parts can build you a motor for $4000.
If that's what you want you will find it on ebay.
If you are in the market for American built V8 engine contact me and let's talk details.
