Chevy Big Block

I have a 1991 Motorhome on a Chev P30 Chassis. The engine is a 454 BB, with no guts. 230 HP about 300 TQ. I need to get this motorhome up to speed. What engine rebuild would you suggest? Heads, Cam, Headers, etc. I looked at the 502, but they are pricey. I can probablyrebuild my engine and get good results? That is a question too.

Additional Information about the motor.

This has the throttle body injection system.

I do not know how to reply to your "posts", but I really appreciate your feedback This is great.

I would just raise the compression ratio to around 9.5:1, and use a RV cam, such as the comp 268H series which reads, "if your doing heavy towing with a big block this is the cam you want" I would also add a edelbrock performer intake or the like. you need lots of torque to move a motor home, and these 2 additions along with a K&N air filter and the best ignition upgrade you can afford will give your 454 a torque increase. I would just upgrade the HEI with a hotter coil and matching module, use a brass terminal cap and use spiral core spark plug wires. You can also add headers and a decent exhaust system with crossover pipe to give it more torque, this will also likely help to increase mileage.

Might also look at an MSD box. This will give you some added throttle response, power, and ecomony at the 3000 and below RPM range.
