Here in California, you would have a hard time convincing a smog Tech this engine swap was viable, even properly equipped. Most likely if allowed the the vehicle would have to have all the original smog equipment as shipped from the OEM, but installing a V8 would be a no-no in any event I believe.. If the vehicle is more than 25 years old smog certs are not required and anything goes...

You know Lake Tahoe banned the use of two-stroke engines. Anything is possible here in the eco state...

Cracker Box boats are something else... What a ride!!!

Ahh , the good old days of Hot Rodding. I have hard time relating relating to the rice burners being hot rodded in todays world. An Olds with a GMC blower? Dick your showing age... I was two years old in "60"...

Dick your exhaust systems are legendary....

On the H9 Sukhoi engine dilemma:

This is an exceptional example of an ARF Aerobat, kudos to Mike McConville and H9. Very well built and engineered, IMO. Not to mention good looking [I have always thought they were UGLY].

Been here recently, presently setting up two models side by side. My son decided RC models were more intriguing than video games and has yet to realize girls are too. One model is set-up with Taurus's 5.7ci single and the second model is rigged with a 3W100-B2-SS light-weight [my son's, he decided he is the 3W kid this is the second model we've rigged with a 3W for him]. Both engines are nearly identical in weight less mufflers [2 ozs. plus to the 5.7]. The engines are within 1/4" of each other for firewall offset to the prop-hub spacer. Neither required engine spacing or spacers. With the BME or the DA you may need spacer's, as they are shorter. However the cowl of the Sukhoi of can be moved back without issue quite far.

You'll have to knock out the existing 1/4" blind nuts and relocate them to accommodate the engine you choose to use without doubt. H9 includes a would adapter/spacer to use a Zenoah engine but I don't think it will help with either the BME or DA.
