Help me with a 347 bench build
Help me with a 347 bench build Currently in my garage, I have an aluminum LS1 out of a 2002 Camaro with a spun rod bearing. The block and rotating assembly have unknown milage on them. The valve train, unfortunately, has about 20 miles on it. It consists of 243 heads, cleaned up and milled to 61cc champers by TEA, factory rockers with comp trunion upgrade, unknown upgraded valve springs from TEA, new pushrods, new LS7 lifters, Vinci cam 216/224 585/585 112, and a new Melling oil pump.
I also have a 1969 Corvette roadster that Im building with a full Ride Tech suspension and Wilwood brakes. The engine will be backed by a TKO600 and the factory 3.80 rear. The biggest tire I can fit in the back is a 9" wide.
What Im looking for is an engine that has very sharp throttle response and revs quickly. Because of the limitations of the factory IRS and 9 inch tire, gobs of low end torque aren't necessarily what Im after. Im looking for a motor with a very linear power band that will be fun to abuse on the back roads and see occasional auto cross duty.
All of that being said, how would you build a motor for this car using the factory aluminum LS1 block? Obviously all of the afore mentioned components are available, but Im really leaning towards just using the block and having something built specifically for this car.
Thanks!

arp rod bolts rods resized because they will be out of round either a torquer cam or a torquer v2, forged pistons to put your heads around 11.5 compression or 11.0 and use a thinner head gasket
