Your right Mark I screwed the pooch on that one , its an 89 top gun, so heavier. Thanks for the reallity check.

700 is easy hp from a natural BBC... and if you want a bit more ad blowers... but bloweres arent treally needed untill about 750 hp..... as a near 10:1 92 octain motor is easilly buildable to 700 hp at 6000... and relitivly cheap to... 5K in parts if you have a good block and heads already. and ported BBC rectangulars do just fine up to that range..

Just keeping you an the straight and narrow. LOL

Mark

very much interested in hearing more info. specs and hints

Here's my 2 cents...
If your cranks and rods are still good keep them and re-piston the bottom end for a 8.0:1CR with high quality Ross or JE sets.
A 250 BlowerShop blower with a set of 750 Holley's for them would be perfect.

10,000 will be 20,000, 20,000 will be 30,000 did thesame thing last winter pulled the little 509s w/250 blower single carb and bought 557 carb motors wasnt going blown. put it on dyno didnt make enough power added 871s, chillers, dual dominators,etc now has plenty of power.started out cheap got deep pretty quick.

They sure look good though!

thank u my warlock brother btw how is the wife?

8 1/2 months pregnant but doing great. Unsure how this is going to affect the boating? So far it means I can't go to the Miami boat show. I figure summer will be about normal except only slooow when the baby is in the boat.

Wanted to close this thread ( and hit my 1000 posts) with some final project info/pics...I ended up rebuilding my blocks to 540's. Kept my stock blocks and cranks...every other part is new. Used all the best parts. Jesel belt drive, Pro-filer heads, custom ground cam, etc. I had the motors port matched, blue printed with superior geometry. On the dyno showing 808HP at 5900 rpm under load. 9.25comp. I'm way happy. I took every aluminum component (except the heads) and sent them out west to be chromed. This keeps the cleaning and polishing to a minimum. The heads & intake work was done by a well known engine team. I upgraded all hoses to Aeroequip lines, added strainers, 3" oil coolers, 14 qt customer pans, etc. I also at the same time rebuild both max machine drives. With all this done & said my $30,000 was well spend at about day 4. While it was decided, I went way beyond $30,000 and discovered you just can't get the best of the best for cheap. I spent almost double with everything to date, and still have some things to do (ie: props) but I think I have a good reliable package, with pretty big power. I need to thanks Mark Rinda at MER Performance for a fantastic job. He is a good honest man who stands behind his work. Takes real pride in is customers.

BTW: I'll be posting over the winter but I have a huge amount of parts for HP500's left over. From heads, to intakes, cams, rockers, oil pans, valves, carbs, etc...I have it all. email me at [email protected] or [email protected] for info.
