Budget build with performance in mind

Post  SDMF on June 26th 2017, 7:33 pm

Hey guys so I've been debating on this subject for about a week and can't really make up my mind. The build will be going in a 68 f 100, it won't be a daily but will get driven so that's something to keep in mind. I'm looking for 450hp to the wheels. So here's my question my block is a 71 and currently has a balanced rotating assembly consisting of 69 rods, 73 pistons and a 79 crank. I'm wanting to up the compression to about 9.5:1 ( heads are 73) the Pistons I've been looking at are the speed pro flat tops and I'm not sure I can get there with this choice? Cam will be a lunati voodoo 262/268, heads will be home ported(exhaust side mainly), performer intake and a 750 Holley. So let's here what everyone has to say.

Thanks
Chris

Spend more time on the heads and intake side, the exhaust side can be easily compensated for in the cam

Those flat-top pistons at their -/020" deck clearance will get to 9.6/1 compression ratio with D3VE heads..  Decking the block to near "0" deck would be much better.

The heads will need larger valves installed with some bowl porting AND a Trick Flow "Track Heat" intake manifold or "Victor port match" on the heads with a Victor intake manifold.  A Performer intake manifold won't get you to the performance level you wish to achieve.

Thanks for the info Randy. Would a performer rpm help? Wanting to keep some drive ability.

Thanks

I understand about the tune, but in my previous experience with the Vic jr's it wasn't a very pleasurable drive until it was up around 4500 then it was a blast ( 5.0's either stock stroke crank or stroked). I'm new to the BBF that's why I'm asking. I do appreciate the responses. That's why I'm asking.

There is no viable comparison to make at all between any type 5.0 small block and a 460 big block.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

If by "driveability" you mean you want to keep some low end grunt...don't worry about it. A guy who's used to 5.0 power is in for a surprise.
