ASE's mission is to improve the quality of vehicle repair and service through the testing and certification of repair and service professionals. Until the early 1970s, consumers had no way to distinguish between incompetent and competent mechanics. In response to this need, the independent, non-profit National Institute for Automotive Service Excellence (ASE) was established in 1972. |

P.A.W. 383 Cubic Inch Stroker EnginePerformance Automotive Warehouse, 21001 Nordhoff Street, Chatsworth, CA 91311 |
Ok, with that said, first off, I have two engines for this 1971 Chevy C-10, one is a 350 c.i. ( which is currently installed in the truck ) and the other is 383 c.i. stroker which is on an engine stand in my garage.
The relatively stock 350 c.i. engine that currently resides in the C-10 is a strong runner without any problems and has quite a bit of life left to it.
The plan for the 1971 C-10's engine modification, i.e., when the day finally comes where the 350 c.i. engine finally gets tired, is to pull out the 350 c.i. engine and swap-in the 383 stroker.
So until it is time for this swap, the 350 c.i. has just been modified with bolt-on items, e.g., there is a March pulley system installed, there's more, but I'll get into that a little later on in another section of this web site.
For now, suffice it to say that all the performance parts on the 350 c.i. engine can be removed and re-installed on the 383 c.i. engine when the time comes for the engine swap.So now that the reader is aware that this engine swap for the C-10 will be taking place sometime in the future, this section of the web site is to give more detailed information about the 383 c.i. stroker engine and the performance parts I have for it.

This beast has a forged 5140 chrome moly steel 400 micropolished crankshaft @ .10 - under ( rod and main journals ) which has lightening holes and computer designed counter-weights to reduce main bearing load plus the crank had a multi-stage heat treatment process to increase its strength and the oil holes are chamfered.
Heavy duty 5.7 inch long rods with chrome moly rod bolts. Shot-peened for strength.
TRW 10:9:1 compression flat top forged pistons with 4 valve reliefs, moly top compression ring and stainless oil ring.
The engine block has an ARP head stud kit installed.
PHOTO M 20 B In order to provide better oil lubrication for the roller timing chain gear set a 0.030 hole was laser cut in the center of the middle oil gallery pipe plug. NOTE : This laser cut plug has been installed in the 350 c.i. engine currently in the 1971 C10. This plug is one of the parts that will be transferred to the 383 c.i. engine. |
Long story short, I ended-up selling the remaining 3 laser cut plugs to fellow gearhead buddies of mine.
It costs about $35.00 to have this 0.030 hole laser cut in the plug, and since I don't have any more of these plugs on hand, this part needs to be transferred over when it is time for the engine swap.
TECHNICAL NOTE : To have this modification perform as an enhancement, the engine needs to have a high volume high pressure oil pump.
NOTE: When I sold the 1971, I left the TAP-EX plug in the 350 engine, so it is not available for transfer. If you want this plug, you will have to contact TAP-EX to make you one.
These high performance cylinder heads have hardened seats, a three-angle valve job with new bronze guides and 2.02" intake and 1.60" exhaust valves installed. Additionally these P.A.W. cylinder heads have screw in studs and guide plates, double valve springs with moly retainers and PC seals.

High Performance Parts Detailed Information
This section provides comprehensive information of the parts listed in PHOTO M 19
Competition Cams incorporate modern technology and design features to create the most advanced aluminum roller rocker arms available.
Proven to withstand extremely aggressive spring pressure, the COMP Cams Ultra Gold aluminum roller rocker arms use their CNC-machined aluminum design for high quality and the ultimate in ratio accuracy.PHOTO M 22 A Photo M 22 A shows an enlarged view of the Competition Cams 3/8 inch stud-mount 1.6 ratio CNC-machined aluminum roller rocker arms to be installed on the 383 c.i. engine for the 1971 C-10. |
As one can see from the spec sheet on this camshaft it has a slightly aggressive profile and in combination with the 1:6 ratio roller rockers will provide good power through the RPM range and excellent low end torque. It will give the C10 a throaty "rumpty-rump" at idle while still maintaining adequate vacuum characteristics. |
Additionally, by Installing this cover, it forever ends the tedious task of breaking the oil pan seal when there is a need ( or want ) to ( 1 ) advance or retard the cam gear, ( 2 ) when it comes time to renew the timing chain, ( 3 ) crankshaft oil seal and ( 4 ) change the camshaft.
Another nice feature about this cover is that camshaft end-play adjustment is made easy thanks to an access hole for the dial indicator.The windage tray needs to be fitted to the block and slightly trimmed for clearance of the rotating assembly in stroker engine blocks. |
This intake manifold is the most advanced dual plane 180 degree intake on the market, combining excellent bottom-end performance with an exceptionally broad power curve that extends to 6800 RPM.
The Stealth intake manifold is designed to be used in conjunction with a more aggressive camshaft profile such as the one listed above for the C10.
NOTE: Due to the enlarged runner castings on this manifold, it will be necessary to raise the valve covers to provide clearance. This is accomplished by using Fel-Pro P/N 1604 5/16 thick valve cover gaskets which are included with the parts listed in PHOTO M 19.

The next section will detail the performance parts already installed on the 350 c.i. engine which is currently in the C10 ( as of April 2011 ) and are to be transferred over to the 383 c.i. stroker.
