You might start by explaining what you want to do with this engine and how did you come to a 500 hp goal. Getting that type of power out of your 302 is not very realistic.

Ok so here are my following reasons why..

1. I live in Reno, NV (5300 feet) power loss is typical up here due to elevation.
So when I tell you guys it's a little over 300 hp that's taking the elevation change, if this was sea level I may be having a different conversation.

2. The current motor is a 302 with GTP40 heads and a mild cam. Motor has 2800 miles on it. I bought it like that back in September. The original owner claimed it was 400hp, it's clearly not that. The power is decent out of 1st and 2nd but once you move from those two gears it just doesn't have enough power to my liking.

3. So to aim for 500hp would give me somewhere around 400 rear wheel at my elevation. I am aware added horse power creates added stress to other parts, however after doing some research it looks like this number is realistic on this block. I am seeing the mustang guys pushing more hp out of the same block.


Last thing I should tell you I do have a budget of 10k.
