A hydraulic cam and lifters are often the best option for a street bar because hydraulic lifts don't require adjustments. They are also quieter, which can be a problem if the engine compartment is open. On the other hand, some people like the sound of a solid lift cam and want the ability to play with valve settings to “adjust the engine”. A couple of hours into assembly and you will have a very affordable and reliable 383 cid performance engine.
Pace's 350 cid (GMP-12530283-HFI) may say “Heavy-Duty Truck Engine”, but in reality, it's a durable everyday driver with Holley Avenger EFI for added reliability and plenty of torque. If you're looking to go fast, have a brilliant engine for your show car or just a reliable mill for your daily driver, and do it on a ramen budget, a cocked engine may be exactly what you're looking for. This combination of engine and EFI is an excellent choice for navigating the city with maximum horsepower and torque below 5,000 rpm. Many of the desirable older engines that would make good street rod motors have been melted for scrap metal or have already been rebuilt once or twice.
Any machine shop doing custom engine rebuilding or engine building work can potentially take advantage of today's street bar market. Since most street rod motors must deliver good driving and power, building an engine that can deliver a large amount of low-end torque is much more important than building an engine for maximum power. Anything goes when it comes to building a street bar, so virtually any engine is a potential prospect for engine work. A much more effective way to promote your services is to engage in conversations with vehicle owners and talk to them about their engines and what you can do for them.
For Hot Rods, Street Rods and everyday drivers, nothing beats the tried and true Chevy small block Gen I engine. A street rod engine that doesn't accelerate much more than a stock engine also doesn't need a lot of valve spring pressure, especially with a flat pusher cam. Using the time-tested ZZ4 short block assembly, the GM HOT Cam is added, which was developed by GM Motorsports for the LT1 and LT4 engines used in exhibition road racing. From the most basic engine assembly to the upper 8-cell EFI drawer, each of these kits represents great value for money.
Cast pistons are OK for most old car and street bar restoration projects because engines are not built for racing, but for everyday street use. Warranty coverage can also be an attractive feature, but since these engines aren't typically used for full performance, the owner is unlikely to outperform normal use anyway.
